Product Name:4-Nitrophenyl-beta-D-galactopyranoside
English Name:4-Nitrophenyl-beta-D-galactopyranoside
CAS No.:3150-24-1
Aliases:PNPG, p-Nitrophenyl beta-D-galactopyranoside, 4-Nitrophenyl beta-D-galactoside
Molecular Formula:C12H15NO8
Physical Properties:White to off-white crystalline powder; soluble in water, methanol, ethanol, DMF and other solvents; hydrolyzes under alkaline conditions to yield yellow p-nitrophenol with maximum absorption at about 405 nm; should be stored at -20 °C, protected from light, sealed and dry.
Uses:Used as a chromogenic substrate for beta-galactosidase. The colorless substrate is hydrolyzed by the enzyme to release p-nitrophenol, which produces a yellow color quantifiable at 405 nm. Widely applied in enzyme kinetics studies, LacZ reporter gene expression assays, and clinical biochemical diagnostic kits.
Technical Specifications:
Appearance: white to off-white crystalline powder, no visible impurities
Purity (HPLC): ≥98%
Molecular weight: 301.25, formula C12H15NO8
Melting point: approximately 180-182 °C
Storage: store at -20 °C, protected from light, sealed and dry
