Thiamine hydrochloride Chemical Properties,Uses,Production


Thiamine Hydrochloride is the hydrochloride salt form of thiamine (vitamin B1), a vitamin essential for aerobic metabolism, cell growth, transmission of nerve impulses and acetylcholine synthesis. Vitamin B1 helps prevent various health problems including heart damage.
Thiamine hydrochloride is used to prevent and treat thiamine deficiency states, which may occur as a result of inadequate nutrition or intestinal malabsorption. It is also used for the treatment of Wernicke-Korsakoff syndrome, beriberi and thiamine deficiency related to chronic alcoholism. Thiamine hydrochloride is used as a food additive to add brothy/meaty flavor to gravies or soups. It is used also as a food supplement and flavoring ingredient with a bitter taste.

Chemical Properties

White or almost white, crystalline powder or colourless crystals.


Thiamine is the water-soluble vitamin b1, required for normal digestion and functioning of nerve tissues and in the prevention of beriberi. It also acts as a coenzyme in the metabolism of carbohydrates. During processing, the higher and longer the heating period, the greater the loss. The loss is reduced in the presence of acid. Thiamine hydrochloride and thiamine mononitrate are two available forms. The mononitrate form is less hygroscopic and more stable than the hydrochloride form, making it suitable for use in beverage powders. It is used in enriched flour and is found as thiamine mononitrite in frozen egg substitute and crackers.


Thiamine is a essential nutrient required for carbohydrate metabolism; also involved in nerve function. Biosynthesized by microorganisms and plants. Dietary sources include whole grains, meat products , vegetables, milk, legumes and fruit. Also present in rice husks and yeast. Converted in vivo to Thiamine diphosphate, a coenzyme in the decarboxylation of α-keto acids. Chronic deficiency may lead t o neurological impairment, bariberi, Wernicke-Korsakoff syndrome.


A cofactor required for oxidation of carbohydrates and for the synthesis of ribose.


ChEBI: A hydrochloride obtained by combining thiamine chloride with one molar equivalent of hydrochloric acid.

Safety Profile

Poison by intravenous and intraperitoneal routes. Mildly toxic by ingestion. The vitamin is destroyed by alkalies and alkaline drugs such as phenobarbital sodium and by oxidzing and reducing agents. When heated to decomposition it emits very toxic fumes of HCl, Cl-, SOx, and NOx.

Purification Methods

The hydrochloride crystallises from 95% EtOH (solubility is ca 1%). The monohydrate is dehydrated at 100o in vacuo over H2SO4, but is hygroscopic and picks up one molecule of H2O readily. It can be sterilised at 100o if the pH of the solution is below 5.5. The nitrate has m 196-200o(dec) and is more stable than the hydrochloride. The picrolonate crystallises from H2O and is dimorphic, m 164-165o and 228-229o(dec). [Todd & Bergel J Chem Soc 364, 367 1937, J Am Chem Soc 58 1063, 1504 1936, 59 526 1937, Beilstein 27 IV 1766.]
