Naphazoline EP Impurity A CAS 36321-43-4

Description

Compared with other compounds in its class, the molecular weight of 228.29 g/mol gives Naphazoline EP Impurity A distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Naphazoline EP Impurity A (CAS 36321-43-4, C14H16N2O) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Naphazoline EP Impurity A (C14H16N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 Naphazoline EP Impurity A 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.
