Chemical Structure

Valsartan Impurity 62 CAS 1314799-75-1 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.

As a process- or degradation-related impurity, Valsartan Impurity 62 (CAS 1314799-75-1, C23H27N3O) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Valsartan Impurity 62 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 361.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
