Chemical Structure

Adefovir Impurity 24 CAS 762-04-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 138.10 g/mol gives Adefovir Impurity 24 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Adefovir Impurity 24 (CAS 762-04-9), a pharmacopoeial impurity reference standard (molecular formula C4H11O3P, MW 138.10 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C4H11O3P, Adefovir Impurity 24 contains a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 138.10 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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 Adefovir Impurity 24 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.
