Chemical Structure

Chlortetracycline Hydrochloride EP Impurity L CAS CATO-C4X-233022 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 460.86 g/mol gives Chlortetracycline Hydrochloride EP Impurity L distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Chlortetracycline Hydrochloride EP Impurity L (CAS CATO-C4X-233022), a pharmacopoeial impurity reference standard (molecular formula C22H21ClN2O7, MW 460.86 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Chlortetracycline Hydrochloride EP Impurity L (C22H21ClN2O7) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 460.86 g/mol, it falls into the moderately-high-molecular-weight range. 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 Chlortetracycline Hydrochloride EP Impurity L 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.
