Chemical Structure
Description
CATO supplies Tirofiban Impurity 93 HCl (CAS CATO-C4X-125493), a pharmacopoeial impurity reference standard (molecular formula C17H18N2O4HCl, MW 350.80 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C17H18N2O4HCl, Tirofiban Impurity 93 HCl contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 350.80 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
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.
