Chemical Structure

Dolutegravir Impurity 64 CAS CATO-C4X-162064 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Dolutegravir Impurity 64.

Dolutegravir Impurity 64 (CAS CATO-C4X-162064) is a certified pharmaceutical impurity reference standard with the molecular formula C19H17F2N3O6C19H15F2N3O5 and a molecular weight of 824.70 g/mol.

Based on its molecular formula C19H17F2N3O6C19H15F2N3O5, Dolutegravir Impurity 64 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 824.70 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

CATO manufactures Dolutegravir Impurity 64 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.
