Product Details
Introduction
4-Nitrophenyl β-D-glucopyranoside (CAS 2492-87-7) is an organic compound with a density of 1.6 ± 0.1 g/cm³, a boiling point of 582.2 ± 50.0°C (760 mmHg), and a melting point of 165–168°C. It serves as a colour-forming substrate for β-D-glucosidase, producing a yellow solution upon enzymatic hydrolysis. It appears as a white to greyish-white or yellow powder and must be stored in a sealed container in a cool, dry place. This substance is classified as acutely toxic (oral Category 4), a skin irritant (Category 3), and toxic to specific target organ systems (single exposure Category 1). Its GHS signal word is "Warning", and it is labelled with the GHS07 and GHS08 pictograms. It is primarily used as a biochemical reagent and in scientific research.
4-nitrophenyl β-D-glucopyranoside is a chromogenic β-D-glucosidase substrate that produces a yellow solution upon cleavage.
