Chemical Structure

LCZ-696 Impurity 16 CAS 1639970-62-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 365.42 g/mol gives LCZ-696 Impurity 16 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, LCZ-696 Impurity 16 (CAS 1639970-62-9, C22H23NO4) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, LCZ-696 Impurity 16 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 365.42 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).

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.
