Formaldehyde is a 37% (saturated) solution stabilized with 10% methanol to limit oxidation and the degree of polymerization. Historically used as an embaliming agent due to its ability to crosslink primary amino groups in proteins through a methylene linkage; however, due to its extremely toxic nature it tends to be avoided. Formaldehyde is also used in numerous industrial applications and organic syntheses; some concern has been raised about the harmful exposure generated when used, or released from products containing it. Research suggests that exposure to Formaldehyde may cause respiratory irritation and an increase in the occurence of myeloid leukemia.

Preparation
Formaldehyde 37% is adjusted to pH 8 and urea is added to give a urea to formaldehyde ratio of about 1 :2.5 molar. The resulting solution is boiled under reflux for 1 hour. Butanol (1.5-2.0 mole per mole of urea) is then added together with a little xylene. The latter forms, with butanol and water, a ternary azeotrope which on distillation yields a condensate separating into an upper organic layer and a lower aqueous layer. By discarding the lower layer and returning the upper layer to the reactor, water is progressively removed from the system. After a substantial proportion of the water has been removed, an acid catalyst (e.g. phosphoric acid or phthalic anhydride) is added and heating is continued. When the required degree of reaction is attained, the solution is neutralized and concentrated to the desired solids content.

Industrial applications
Formaldehyde 37% is a common precursor to more complex compounds and materials. In approximate order of decreasing consumption, products generated from formaldehyde include urea formaldehyde resin, melamine resin, phenol Formaldehyde 37% resin, polyoxymethylene plastics, 1,4-butanediol, and methylene diphenyl diisocyanate.The textile industry uses formaldehyde-based resins as finishers to make fabrics crease-resistant.
When treated with phenol, urea, or melamine, formaldehyde produces, respectively, hard thermoset phenol formaldehyde resin, urea formaldehyde resin, and melamine resin. These polymers are permanent adhesives used in plywood and carpeting. They are also foamed to make insulation, or cast into moulded products. Production of formaldehyde resins accounts for more than half of formaldehyde consumption.
Formaldehyde 37% is also a precursor to polyfunctional alcohols such as pentaerythritol, which is used to make paints and explosives. Other formaldehyde derivatives include methylene diphenyl diisocyanate, an important component in polyurethane paints and foams, and hexamine, which is used in phenol-formaldehyde resins as well as the explosive RDX.
Condensation with acetaldehyde affords pentaerythritol, a chemical necessary in synthesizing PETN, a high explosive.Condensation with phenols gives phenol-formaldehyde resins.
