About Lactulose EP Impurity B

Lactulose EP Impurity B (CAS 10257-28-0) is a pharmacopeial impurity of Lactulose offered by Vaqora Chemicals. Its molecular formula is C6H12O6 and its molecular weight is 180.16 g/mol. Systematically, it is named (3R,4S,5R,6R)-6-(hydroxymethyl)oxane-2,3,4,5-tetrol. Alternative names: Lactulose - Impurity B and D-Galactopyranose.

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. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

Pharmaceutical QC and development laboratories use this impurity standard of Lactulose to develop and validate HPLC methods, to set specification limits and to document impurity profiles in ANDA and DMF submissions. Our customers for this product work in 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.
