Cas no 4419-94-7 (p-Nitrophenyl b-D-Lactopyranoside)

Technical Introduction: p-Nitrophenyl β-D-lactopyranoside is a synthetic chromogenic substrate widely used in enzymatic assays, particularly for studying β-galactosidase activity. Its key advantage lies in the release of p-nitrophenol upon enzymatic hydrolysis, which produces a measurable yellow color change detectable at 405–420 nm, enabling quantitative spectrophotometric analysis. This substrate offers high sensitivity and specificity for β-galactosidase, making it valuable in biochemical research, diagnostics, and quality control applications. The compound’s stability under standard laboratory conditions and its water solubility further enhance its utility in kinetic studies and enzyme characterization. Its reliable performance ensures reproducible results in both academic and industrial settings.
