Used as a protected form of riboflavin (vitamin B2) in pharmaceutical and nutraceutical formulations. It serves as an intermediate in the synthesis of flavin cofactors such as flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD). Due to its enhanced stability and lipophilicity compared to free riboflavin, it is employed in transdermal delivery systems and sustained-release preparations. Commonly found in cosmetic products for skin conditioning and antioxidant protection. Also utilized in cell culture media and enzymatic assays where controlled release of active riboflavin is required.
