Chemical Structure

Trazodone Impurity 71 CAS CATO-C4X-177271 chemical structure

Description

CATO supplies Trazodone Impurity 71 (CAS CATO-C4X-177271), a pharmacopoeial impurity reference standard (molecular formula C7H14ClN3O, MW 191.66 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Trazodone Impurity 71 (C7H14ClN3O) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
