Chemical Structure

阿托伐他汀杂质13 CAS 2204368-96-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 177.20 g/mol gives 阿托伐他汀杂质13 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 阿托伐他汀杂质13 (CAS 2204368-96-5), a pharmacopoeial impurity reference standard (molecular formula C7H15NO4, MW 177.20 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 阿托伐他汀杂质13 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 177.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
