Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 454.64 g/mol gives Ubidecarenone Impurity 14 (Coenzyme Q4) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ubidecarenone Impurity 14 (Coenzyme Q4) (CAS 4370-62-1) is a certified pharmaceutical impurity reference standard with the molecular formula C29H42O4 and a molecular weight of 454.64 g/mol.
Owing to a steroid core, a hydroxyl group, an ether linkage, Ubidecarenone Impurity 14 (Coenzyme Q4) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 454.64 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).
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.
