Product Detail


Product Name:Riboflavin

CAS Number:83-88-5

Yellow to orange/yellow crystalline powd

A water-soluble B fraction was found in the 1920s to contain a yellow, fluorescent growth factor called riboflavin in England and vitamin G in the United States. In the early 1930s, several groups found the coenzyme forms of riboflavin 50-phosphate (flavin mononucleotide) and the further conjugate with adenylic acid (flavin adenine dinucleotide).

VITAMIN B2 (Riboflavin). Some earlier designations for this substance included vitamin G, lactoflavin, hepatoflavin, ovoflavin, verdoflavin. The chemical name is 6,7-dimethyl-9-d-l’ribityl isolloxazine. Riboflavin is a complex pigment with a green fluorescence.

Riboflavin is moderately soluble in water (10–13 mg/dl) and ethanol but insoluble in ether, chloroform, and acetone. It is soluble but unstable under alkaline conditions.
The catalytic functions of riboflavin are carried out primarily at positions N-1, N-5, and C-4 of the isoalloxazine nucleus. In addition, the methyl group at C-8 participates in covalent bonding with enzyme proteins. The flavin coenzymes are highly versatile redox cofactors because they can participate in either one- or two electron redox reactions.Riboflavin antagonists include analogs of the isoalloxazine ring (e.g., diethylri boflavin, dichlororiboflavin) and the ribityl side chain (e.g., d-araboflavin, d-galactoflavin, 7-ethylriboflavin).
