Chemical Structure

Aciclovir Impurity 34 CAS CATO-C4X-101034 chemical structure

Description

CATO supplies Aciclovir Impurity 34 (CAS CATO-C4X-101034), a pharmacopoeial impurity reference standard (molecular formula C17H21N11O7, MW 491.42 g/mol) used for the identification and quantification of trace impurities in APIs.

Aciclovir Impurity 34 (C17H21N11O7) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

As a certified reference material (CRM), Aciclovir Impurity 34 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
