Riboflavin 5'-phosphate sodium

Riboflavin 5'-phosphate sodium (CAS 130-40-5), also known as FMN sodium salt or flavin mononucleotide, is the phosphorylated, water-soluble form of vitamin B2. It is commercially referenced under names including Cytoflav, Flamotide, and Coflavinase, and functions as a coenzyme in cellular oxidation-reduction reactions.

In cosmetic formulations, it acts as a skin conditioner and protectant by supporting cellular energy metabolism and neutralising free radicals at the dermal level. In food and pharmaceutical manufacturing, it serves as a yellow-orange colorant and antioxidant stabiliser, where its photosensitive properties must be controlled through formulation design.

Riboflavin 5'-phosphate sodium is supplied as a fine powder in pharmaceutical and food-grade specifications, compliant with Ph.Eur., FCC, and REACH requirements. It falls under HS code 29362300 and is available in quantities suited to both development-scale and industrial procurement.
