Atosiban Impurity 35 CAS CATO-C4X-229335

Description

Compared with other compounds in its class, the molecular weight of 937.14 g/mol gives Atosiban Impurity 35 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Atosiban Impurity 35 (CAS CATO-C4X-229335) is a certified pharmaceutical impurity reference standard with the molecular formula C41H64N10O11S2 and a molecular weight of 937.14 g/mol.

Atosiban Impurity 35 (C41H64N10O11S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 Atosiban Impurity 35 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.
