Adapalene EP Impurity C CAS 43109-77-9

Description

Compared with other compounds in its class, the molecular weight of 242.36 g/mol gives Adapalene EP Impurity C distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Adapalene EP Impurity C (CAS 43109-77-9), a pharmacopoeial impurity reference standard (molecular formula C17H22O, MW 242.36 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a steroid core, a hydroxyl group, an ether linkage, Adapalene EP Impurity C is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 242.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 Adapalene 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.
