Tirofiban Impurity 24 CAS 149490-61-9

Description

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Tirofiban Impurity 24 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 434.55 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies Tirofiban Impurity 24 (CAS 149490-61-9), a pharmacopoeial impurity reference standard (molecular formula C22H30N2O5S, MW 434.55 g/mol) used for the identification and quantification of trace impurities in APIs.

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.
