Description
CATO manufactures Ritonavir EP Impurity F 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.
Ritonavir EP Impurity F (CAS 1010809-61-6) is a certified pharmaceutical impurity reference standard with the molecular formula C29H34N4O5S and a molecular weight of 550.67 g/mol.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Ritonavir EP Impurity F is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 550.67 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
