Thiamine hydrochloride is a synthetic form of Vitamin B1, essential for carbohydrate metabolism, nerve function, and energy production. It’s widely used in pharmaceuticals, animal feed supplements, and fortified foods to prevent deficiencies like beriberi. It also serves as a food flavouring additive that gives soups and gravies a brothy, meaty note, and as a biochemical and analytical reagent. This white crystalline powder has a CAS number of 67-03-8, molecular formula C12H17ClN4OS·HCl, and a molecular weight of 337.27. It is stable at ambient temperatures but requires careful handling due to its "Warning" signal word classification. Molekula supplies Thiamine hydrochloride from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
