Description
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.
Ubidecarenone Impurity 25 (Dihydrocoenzyme Q10) (CAS 992-78-9) is a certified pharmaceutical impurity reference standard with the molecular formula C59H92O4 and a molecular weight of 865.36 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Ubidecarenone Impurity 25 (Dihydrocoenzyme Q10) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 865.36 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 manufactures Ubidecarenone Impurity 25 (Dihydrocoenzyme Q10) under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
