DESCRIPTION
3-Pyridinecarboxamide is the systematic registry-style name of the compound commonly known as nicotinamide or niacinamide.
3-Pyridinecarboxamide is identified by CAS Number 98-92-0 and EC Number 202-713-4.
3-Pyridinecarboxamide has the molecular formula C₆H₆N₂O.
3-Pyridinecarboxamide has a molecular weight of approximately 122.12 g/mol.
Structurally, 3-Pyridinecarboxamide consists of a six-membered aromatic pyridine ring bearing a carboxamide group at the 3-position.
The molecule contains one ring nitrogen atom, one carbonyl oxygen atom, and one primary amide nitrogen atom.
The pyridine nitrogen functions principally as a hydrogen-bond acceptor and weakly basic coordination site.
The amide group provides one carbonyl acceptor and amino hydrogen-bond donors.
3-Pyridinecarboxamide is the amide derivative of nicotinic acid.
3-Pyridinecarboxamide and nicotinic acid are chemically distinct forms of vitamin B3 and should not be treated as identical raw materials.
3-Pyridinecarboxamide does not normally cause the vasodilatory flushing associated with supplemental nicotinic acid.
3-Pyridinecarboxamide has a different acid–base profile, melting point, solubility pattern, and pharmacological behavior from nicotinic acid.
3-Pyridinecarboxamide normally appears as a white crystalline powder or as colorless crystals.
3-Pyridinecarboxamide is generally described as odorless and may possess a bitter taste.
3-Pyridinecarboxamide commercial grades may differ in crystal habit, particle size, bulk density, flowability, moisture, and color.
3-Pyridinecarboxamide appearance can change after contamination, prolonged heat exposure, or unsuitable humid storage.
3-Pyridinecarboxamide has a representative melting range of approximately 127–131°C.
3-Pyridinecarboxamide may sublime under suitable reduced-pressure or elevated-temperature conditions.
3-Pyridinecarboxamide should not be assigned a simple normal boiling point for routine processing because thermal behavior depends on pressure and exposure time.
3-Pyridinecarboxamide prolonged or excessive heating can cause discoloration, decomposition, and loss of vitamin quality.
3-Pyridinecarboxamide has a representative density of approximately 1.4 g/cm³.
3-Pyridinecarboxamide is highly soluble in water, with international safety information reporting approximately 100 g per 100 mL at 20°C.
3-Pyridinecarboxamide is also soluble in alcohol and selected other polar solvents.
3-Pyridinecarboxamide high aqueous solubility supports concentrated solutions but can also promote crystallization when temperature or water content changes.
3-Pyridinecarboxamide has a reported log octanol–water partition coefficient near −0.38.
3-Pyridinecarboxamide therefore shows a strong preference for aqueous phases rather than nonpolar oil phases.
3-Pyridinecarboxamide ordinarily requires dissolution in the water phase of cosmetic, food, feed, and pharmaceutical formulations.
3-Pyridinecarboxamide incorporation into anhydrous or oil-rich products requires a suitable carrier, dispersed phase, encapsulation system, or other formulation strategy.
3-Pyridinecarboxamide is one of the dietary compounds collectively described as niacin or vitamin B3.
Absorbed niacin compounds are converted into nicotinamide-containing coenzymes, particularly NAD and NADP.
NAD participates extensively in metabolic oxidation–reduction reactions and additional cellular regulatory processes.
NADP supports biosynthetic reactions and cellular antioxidant functions.
3-Pyridinecarboxamide is present naturally or metabolically in foods, living organisms, and biological samples.
Dietary sources of niacin include meat, poultry, fish, grains, legumes, nuts, and fortified foods.
The body can also derive niacin equivalents from the amino acid tryptophan.
Commercial 3-Pyridinecarboxamide provides a standardized free form that is highly bioavailable in fortified products.
3-Pyridinecarboxamide can be manufactured by reacting nicotinic acid or a nicotinic-acid derivative with ammonia.
The amidation process requires removal of reaction water and control of ammonium nicotinate and nicotinic-acid impurities.
Crude product may be dissolved, treated with adsorbents or ion-exchange materials, filtered, crystallized, centrifuged, and dried.
High-purity production requires control of color, residual acid, inorganic salts, water, and related pyridine compounds.
3-Pyridinecarboxamide can also be produced through catalytic hydration of 3-cyanopyridine.
The nitrile group is converted into a primary amide through addition of water under catalytic conditions.
Process design aims to maximize amide selectivity while minimizing further hydrolysis to nicotinic acid.
Catalyst selection, temperature, residence time, pH, water ratio, and purification conditions influence yield and impurity formation.
3-Pyridinecarboxamide purification can involve activated carbon, crystallization, ion exchange, weak-base resin treatment, washing, and vacuum drying.
These operations remove colored substances, ionic impurities, nicotinic acid, ammonium salts, and trace process residues.
Food, pharmaceutical, feed, cosmetic, and analytical grades can have different purity and contaminant requirements.
The certificate of analysis for the selected grade should determine suitability for the intended application.
3-Pyridinecarboxamide is generally stable under appropriate cool, dry, and protected storage conditions.
Strong oxidizing agents are incompatible with the substance.
Combustion can produce toxic or irritating gases, including nitrogen oxides.
Repeated exposure to excessive heat, reactive chemicals, or contamination can impair assay, color, and performance.
3-Pyridinecarboxamide is combustible and has a reported flash point near 182°C.
3-Pyridinecarboxamide has a reported autoignition temperature near 480°C.
Fine powder dispersed in air can form an explosive dust mixture.
Large-scale dry processing should therefore control dust accumulation, ignition sources, static discharge, and confinement.
3-Pyridinecarboxamide has low practical volatility as a crystalline solid at ordinary room temperature.
Occupational inhalation exposure occurs principally through airborne powder rather than through evaporation.
A nuisance-causing concentration of particles can develop quickly when fine material is poured, ground, conveyed, or mixed.
Local exhaust ventilation and low-dust transfer procedures are therefore important during bulk handling.
3-Pyridinecarboxamide is classified in the cited international safety information as irritating to the eyes.
Direct exposure can cause redness and pain.
Some classification notifications also identify skin or respiratory irritation, although the harmonized profile should be confirmed from the current regional documentation.
The latest grade-specific Safety Data Sheet should determine labeling, personal protection, and emergency procedures.
3-Pyridinecarboxamide high nutritional or pharmacological intake is not equivalent to ordinary occupational exposure to the raw powder.
Very high supplemental intake can produce adverse effects despite the material’s vitamin function.
Nutritional, pharmaceutical, cosmetic, and industrial exposure assessments therefore require different assumptions and controls.
Therapeutic or high-dose use should occur only under appropriate professional and regulatory oversight.
3-Pyridinecarboxamide is highly water soluble and is expected to move readily with aqueous waste streams.
Release to drains should be controlled despite its nutritional identity.
Concentrated material can increase chemical oxygen demand, alter microbial systems, and expose aquatic environments unnecessarily.
Wastewater decisions should consider total quantity, other formulation ingredients, local treatment capability, and regulatory limits.
3-Pyridinecarboxamide quality control commonly includes appearance, identity, assay, melting range, water, pH, residue on ignition, and related substances.
Food and pharmaceutical grades may include limits for heavy metals, residual solvents, microbial quality, and specific pyridine impurities.
Feed grades may additionally be controlled for particle size, bulk density, flowability, premix uniformity, and storage stability.
Analytical grades require traceable characterization and accurate correction for moisture and purity.
