Thiamine chloride hydrochloride

The free base is unstable, and two derivatives of thiamin are commonly used in food enrichment and pharmaceutical preparations thiamin chloride hydrochloride (generally known simply as thiaminhydrochloride) and thiamin mononitrate. The mononitrate is less hygroscopic than the chloride hydrochloride and is the preferred form for food enrichment. There is considerable difficulty in interpreting much of the literature on thiamin requirements, because many authors quote mg of thiamin, without specifying whether it was as the free base, the chloride hydrochloride, or the equivalent amount of free base. Because the Mr of free thiamin is 266.4, and that of the chloride hydrochloride is 337.3, this confusion can result in errors of the order of 26%. [Pg.150]
