Mevastatin Impurity 1 CAS CATO-C4X-21741 chemical structure

Description

Mevastatin Impurity 1 (CAS CATO-C4X-21741) is a certified pharmaceutical impurity reference standard with the molecular formula C23H35NaO6 and a molecular weight of 430.51 g/mol.

Mevastatin Impurity 1 (C23H35NaO6) contains a steroid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
