How do I get lot-specific information or a Certificate of Analysis?
A Certificate of Analysis is available by lot number and can be obtained through our Advanced Search Option: http://www.sigmaaldrich.com/catalog/AdvancedSearchPage.do
What is the solubility of 4-Nitrophenyl α-D-glucopyranoside, Product N1377?
We test the solubility of 4-Nitrophenyl α-D-glucopyranoside at 20 mg/mL in methanol.  When 4-Nitrophenyl α-D-glucopyranoside is used as a substrate for α-glucosidase, a 4 mM stock solution is made in water.
What is the melting point and specific rotation for 4-Nitrophenyl α-D-glucopyranoside, Product N1377?
The melting point range from our MSDS is 209-213 °C.  The optical rotation is lot specific, and can be found on the Certificate of Analysis at our website.
How is 4-Nitrophenyl α-D-glucopyranoside, Product N1377, used?
4-Nitrophenyl α-D-glucopyranoside is used as a substrate for the assay of α-glucosidase.  A stock solution of 4 mM is prepared in deionized water.  Upon the enzymatic hydrolysis of this substrate, 4-nitrophenol is produced.  The molar extinction coefficient of 4-nitrophenol in 0.01 M NaOH (pH 10.2) is approximately 18,380 at 400 nm.
