Chemical Structure

Repaglinide impurity 27 CAS CATO-C4X-118627 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 450.57 g/mol gives Repaglinide impurity 27 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Repaglinide impurity 27 (CAS CATO-C4X-118627), a pharmacopoeial impurity reference standard (molecular formula C27H34N2O4, MW 450.57 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Repaglinide impurity 27 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 450.57 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.
