Riboflavin 5'-monophosphate (sodium salt hydrate)

FMN (Riboflavin 5'-monophosphate) is a tightly bound redox coenzyme for numerous oxidoreductases and a key ligand for the FMN riboswitch, regulating gene expression. It serves as a critical substrate for phosphohydrolase studies and is widely used in enzymatic research, including in vitro assays and investigations into metabolic pathways.
