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 Clarithromycin EP Impurity J(Roxithromycin EP Impurity C) (CAS 111321-02-9), a pharmacopoeial impurity reference standard (molecular formula C37H68N2O13, MW 748.94 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Clarithromycin EP Impurity J(Roxithromycin EP Impurity C) is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 748.94 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures Clarithromycin EP Impurity J(Roxithromycin EP Impurity C) 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.
