Chemical Structure

LCZ-696 Impurity 58 CAS 1012341-48-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 381.46 g/mol gives LCZ-696 Impurity 58 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies LCZ-696 Impurity 58 (CAS 1012341-48-8), a pharmacopoeial impurity reference standard (molecular formula C23H27NO4, MW 381.46 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, LCZ-696 Impurity 58 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 381.46 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).

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.
