Project Description

Chemical Name Vitamin H / D-biotin
CAS No. 58-85-5
Molecular Formula: C₁₀H₁₆N₂O₃S
EINECS 200-399-3
Molecular Weight: 244.31
Applications: D-Biotin is a growth factor present in minute amounts in every living cell. Plays an indispensable role in numerous naturally occurring carboxylation reactions. Occurs mainly bound to proteins or polypeptides. The richest sources are liver, kidney, pancreas, yeast, and milk. The biotin content of cancerous tumors is higher than that of normal tissue.


1.Biotin is a member of the B complex family, called also vitamin H, coenzyme

2.It is a kind of water soluble Vitamin, acts as a coenzyme during the metabolism of protein, fats, and carbohydrates, maintaining healthy skin and hair, and as necessary material for growth, digestion, and muscle function.
