Molecular Weight: 337.3
CAS No.: 67-03-8
Product name:Thiamine Hydrochloride (Vitamin B1)
Description
Thiamine Hydrochloride occurs as a white or almost white, crystalline powder or colourless crystals. When exposed to air, the anhydrous product rapidly absorbs about 4% of water. It melts at about 248° with some decomposition. One gram dissolves in about 1 mL of water and in about 100 mL of alcohol. It is soluble in glycerin, and is insoluble in ether.
