Chemical Structure

Etoricoxib impurity 62 CAS CATO-C4X-108062 chemical structure

Description

Etoricoxib impurity 62 (C5H9ClN2HCl) contains chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO supplies Etoricoxib impurity 62 (CAS CATO-C4X-108062), a pharmacopoeial impurity reference standard (molecular formula C5H9ClN2HCl, MW 169.05 g/mol) used for the identification and quantification of trace impurities in APIs.

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.
