Chemical Structure

Lamivudine EP Impurity F-13C-15N2 CAS 181517-11-3 chemical structure

Description

Lamivudine EP Impurity F-13C-15N2 (CAS 181517-11-3) is a certified pharmaceutical impurity reference standard with the molecular formula C3[13C]H4[15N]2O2 and a molecular weight of 115.07 g/mol.

Lamivudine EP Impurity F-13C-15N2 (C3[13C]H4[15N]2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 Lamivudine EP Impurity F-13C-15N2 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.
