Chemical Structure

Acyclovir Identification Reference (API& EP Impurity C & EP Impurity I Mixture) CAS CATO-C4X-101027 chemical structure

Description

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 supplies Acyclovir Identification Reference (API& EP Impurity C & EP Impurity I Mixture) (CAS CATO-C4X-101027), a pharmacopoeial impurity reference standard (molecular formula N/A, MW N/A g/mol) used for the identification and quantification of trace impurities in APIs.

Acyclovir Identification Reference (API& EP Impurity C & EP Impurity I Mixture) is supplied as a fully characterized reference material; its structural identity, assigned purity, and stability data are documented in the batch-specific Certificate of Analysis (COA).

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
