E508 Potassium chloride contains 52% of elemental potassium by mass.
Overdose causes hyperkalemia which can disrupt cell signaling to the extent that the heart will stop, reversibly in the case of some open heart surgeries.

E508 Potassium chloride can be used as a salt substitute for food, but due to its weak, bitter, unsalty flavor, it is often mixed with ordinary table salt (sodium chloride) to improve the taste, to form low sodium salt. 
The addition of 1 ppm of thaumatin considerably reduces this bitterness.
Complaints of bitterness or a chemical or metallic taste are also reported with potassium chloride used in food.

The World Health Organization guideline Use of lower-sodium salt substitutes strongly recommends reducing sodium intake to less than 2 g/day and conditionally recommends replacing regular table salt with lower-sodium salt substitutes that contain potassium. 
This recommendation is intended for adults (not pregnant women or children) in general populations, excluding individuals with kidney impairments or with other circumstances or conditions that might compromise potassium excretion.

In the United States, E508 Potassium chloride is used as the final drug in the three-injection sequence of lethal injection as a form of capital punishment. 
E508 Potassium chloride induces cardiac arrest, ultimately killing the inmate.
E508 Potassium chloride is used to prevent or to treat low blood levels of potassium (hypokalemia).

E508 Potassium chloride is used in the chlor-alkaline industry for production of Potassium Hydroxide (KOH) and Potassium Carbonate, as a raw material for the production of Potassium Peroxide and in the production of metal uxes and metal surface treatments.
Potassium chloride is also used as a substitute for common salt (sodium chloride) in food.
Oral consumption of appropriate quantities of KCl can help treat low blood potassium in humans.

E508 Potassium chloride works by replacing lost potassium and preventing a deciency.
E508 Potassium chloride is a potassium salt used to treat hypokalemia.

E508 Potassium chloride is a medicine used to prevent or treat low potassium levels in the body.
A white crystal or crystalline powder used as an electrolyte replenisher, in the treatment of hypokalemia, in buer solutions, and in fertilizers and explosives.

E508 Potassium chloride tablets become increasingly hard on storage at low humidities. 
However, tablets stored at 76% relative humidity showed no increase or only a slight increase in hardness.
The addition of lubricants, such as 2% w/w magnesium stearate, reduces tablet hardness and hardness on aging.

Aqueous potassium chloride solutions may be sterilized by autoclaving or by filtration.
E508 Potassium chloride is stable and should be stored in a well-closed container in a cool, dry place.

E508 Potassium chloride is used in drug preparations and as a food additive and chemical reagent. 
E508 Potassium chloride is possible to reduce the sodium in your diet by substituting potassium chloride for table salt (sodium chloride), which may be healthier. 
Molten potassium chloride is also used in the electrolytic production of metallic potassium. 

E508 Potassium chloride is also found in seawater brine and can be extracted from the mineral carnallite.
E508 Potassium chloride is a widely used reagent in biochemistry and molecular biology. 
It is a component of phosphate buffered saline (PBS, Product No. P 3813) and of polymerase chain reaction (PCR) buffer (50 mM KCl).

E508 Potassium chloride is also used in studies of ion transport and potassium channels.
E508 Potassium chloride is also utilized in the solubilization, extraction, purification, and crystallization of proteins.
The use of E508 Potassium chloride in the crystallization of histone core octamers has been reported.

About 4-5% of potash production is used in industrial applications (UNIDOIFDC, 1998). 
In 1996, the world supply of industrial grade potash was close to 1.35 Mt K2O. 
This industrial material is 98-99% pure, compared with the agricultural potash specification of 60% K2O minimum (equivalent to 95% KCl). 

Industrial potash should contain at least 62% K2O and have very low levels of Na, Mg, Ca, SO4 and Br. 
This high-grade potash is produced by only a few producers in worldwide.
E508 Potassium chloride, commonly referred to as muriate of potash, is the most common source of potash (K2O), and accounts for about 95 % of world potash production. 

Virtually all (90 %) commercial potash is extracted from natural sources of potassium salt deposits occurring in thin beds in large salt basins formed by the evaporation of ancient seas. 
Present-day salt lakes and natural brines represent about 10 % of total recoverable potash. 
Extraction is followed by milling, washing, screening, flotation, crystallization, refining and drying.

More than 90 % of the total E508 Potassium chloride consumption is used for fertilizer production. 
Production of potassium hydroxide accounts for more than 90 % of the non-fertilizer or industrial use of E508 Potassium chloride. 
KOH is also used in the production of some agricultural-grade liquid fertilizers, uses of E508 Potassium chloride include:

Safety Profile Of E508 Potassium chloride:
Potassium ions play an important role in cellular metabolism and imbalances can result in serious clinical effects. 
Orally ingested potassium chloride is rapidly absorbed from the gastrointestinal tract and excreted by the kidneys. 

E508 Potassium chloride is more irritant than sodium chloride when adminstered orally, and ingestion of large quantities of potassium chloride can cause effects such as gastrointestinal irritation, nausea, vomiting, and diarrhea.
High localized concentrations of potassium chloride in the gastrointestinal tract can cause ulceration: hence the development of the many enteric-coated and wax matrix sustained-release preparations that are available.

Although E508 Potassium chloride is claimed that some formulations cause less ulceration than others, it is often preferred to administer potassium chloride as an aqueous solution. 
However, solutions have also been associated with problems, mainly due to their unpleasant taste.
A human poison by ingestion. 

Poison experimentally by ingestion, intravenous, and intraperitoneal routes. 
Human systemic effects by ingestion: nausea, blood clotting changes, carhac arrhythmias. 
An eye irritant, mutation data reported. 

Explosive reaction with BrF3; sulfuric acid + E508 Potassium chloride permanganate. 
When heated to decomposition it emits toxic fumes of K2O and Cl-.
E508 Potassium chloride is used in a large number of pharmaceutical formulations, including oral, parenteral, and topical preparations, both as an excipient and as a therapeutic agent.
