Chemical Structure

Idebenone Impurity 5 CAS CATO-C4X-30165 chemical structure

Description

Owing to a steroid core, a hydroxyl group, an ether linkage, Idebenone Impurity 5 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 308.41 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).

CATO supplies Idebenone Impurity 5 (CAS CATO-C4X-30165), a pharmacopoeial impurity reference standard (molecular formula C18H28O4, MW 308.41 g/mol) used for the identification and quantification of trace impurities in APIs.

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.
