Chemical Structure

Pidotimod Impurity 24 CAS 161771-75-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 244.27 g/mol gives Pidotimod Impurity 24 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Pidotimod Impurity 24 (CAS 161771-75-1), a pharmacopoeial impurity reference standard (molecular formula C9H12N2O4S, MW 244.27 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Pidotimod Impurity 24 (C9H12N2O4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 244.27 g/mol, it falls into the medium-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 Pidotimod Impurity 24 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.
