Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 624.53 g/mol gives Pinaverium impurity 31 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Pinaverium impurity 31 (CAS CATO-C4X-246731), a pharmacopoeial impurity reference standard (molecular formula C26H41BrNO4C2F3O2, MW 624.53 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Pinaverium impurity 31 (C26H41BrNO4C2F3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 624.53 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
