Chemical Structure

Atosiban Impurity 10 CAS CATO-C4X-229310 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 937.14 g/mol gives Atosiban Impurity 10 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Atosiban Impurity 10 (CAS CATO-C4X-229310), a pharmacopoeial impurity reference standard (molecular formula C41H64N10O11S2, MW 937.14 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Atosiban Impurity 10 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 937.14 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
