DESCRIPTION
Biotin occurs as a practically white, crystalline powder. It is stable to air and heat. One-gram dissolves in about 5000 mL of water at 25C and in about 1300 mL of alcohol; it is more soluble in hot water and in dilute alkali, and it is insoluble in other common organic solvents.
Function Nutrient.
REQUIREMENTS
Identification:
A. The infrared absorption spectrum of a potassium bromide dispersion of the sample exhibits relative maxima at the same wavelengths as those of a similar preparation of USP Biotin Reference Standard.
B. A saturated solution of sample in warm water decolorizes bromine, added dropwise.
Assay: Not less than 97.5% and not more than 100.5% of C10H16N2O3S.
Lead: Not more than 2 mg/kg.
Melting Range: Between 229C and 232C, with decomposition.
Optical (Specific) Rotation [α]D 20°: Between +89° and +93°.
Biotin is also available as BP Ph Eur monograph.
