Chemical Structure

(1R,2S,5R)-Lamivudine Impurity 32 CAS 147126-62-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (1R,2S,5R)-Lamivudine Impurity 32.

(1R,2S,5R)-Lamivudine Impurity 32 (CAS 147126-62-3) is a certified pharmaceutical impurity reference standard with the molecular formula C14H24O4S and a molecular weight of 288.40 g/mol.

(1R,2S,5R)-Lamivudine Impurity 32 (C14H24O4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

CATO manufactures (1R,2S,5R)-Lamivudine Impurity 32 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
