Chemical Structure

Lurasidone Impurity 22 CAS 1072-95-3 chemical structure

Description

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.

CATO supplies Lurasidone Impurity 22 (CAS 1072-95-3), a pharmacopoeial impurity reference standard (molecular formula C7H13Cl, MW 132.63 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Lurasidone Impurity 22 (C7H13Cl) is characterized by chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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.

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.
