About Lactulose EP Impurity A

Lactulose EP Impurity A (CAS 20869-27-6) is a pharmacopeial impurity of Lactulose offered by Vaqora Chemicals. Its molecular formula is C12H22O11 and its molecular weight is 342.3 g/mol. Its systematic (IUPAC) name is (2S,3R,4R,5R)-2,3,5,6-tetrahydroxy-4-[(2S,3R,4S,5R,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxyhexanal. Common synonyms include Epilactose and Galbeta-1-4-man.

It is supplied as a solid. Keep the vial tightly closed, protected from light and humidity, at the temperature stated on the Certificate of Analysis. Good laboratory practice and suitable PPE are recommended during handling.

This Lactulose impurity supports analytical method development and validation (AMV), batch release testing and the impurity sections of ANDA and DMF filings. It is used across pharmaceutical manufacturing and academic and industrial research.

Standard pack sizes are 10 mg, 25 mg, 50 mg and 100 mg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
