AFG Scientific 4-Nitrophenyl-alpha-D-glucopyranoside 1 GR – CAS 3767-28-0

4-Nitrophenyl-alpha-D-glucopyranoside (PNPG) is a widely-used chromogenic substrate for spectrophotometric measurement of alpha-glucosidase enzyme activity. Supplied by AFG Scientific at ≥98% purity (HPLC), this product is suitable for reliable results in clinical biochemistry and enzymology laboratories.

Appearing as a white to pale yellowish crystalline powder, the compound releases yellow-colored p-nitrophenol upon enzymatic hydrolysis, enabling colorimetric quantification. With a molecular formula of C12H15NO8 and molecular weight of 301.25 g/mol, this compound must be stored at 0-8°C.

The high purity level verified by HPLC supports assay reproducibility and result reliability. The 1 gram packaging represents a practical choice for small-scale research and routine testing applications.
