CAS 18997-57-4 — 4-Methylumbelliferyl-β-D-glucopyranosid

4-Methylumbelliferyl-beta-D-glucopyranoside (MUG) is a fluorogenic substrate widely used in biochemical assays to detect beta-glucosidase activity, producing a fluorescent product upon enzymatic cleavage. It is essential in microbiology for identifying beta-glucosidase-producing bacteria, such as *E. coli*, and in research for studying enzyme kinetics. This compound has a CAS number of 18997-57-4, a molecular formula of C16H18O8, and a molecular weight of 338.31 g/mol. It requires storage at -15 to -20°C but carries no signal word for hazard classification. Molekula supplies 4-Methylumbelliferyl-beta-D-glucopyranoside from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
