Chemical Structure
Description
The occurrence of Ipragliflozin Impurity 1 is closely related to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ipragliflozin Impurity 1 (CAS 2602662-34-8) is a certified pharmaceutical impurity reference standard with the molecular formula C21H21FO5S and a molecular weight of 404.45 g/mol.
Owing to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, Ipragliflozin Impurity 1 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 404.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 Ipragliflozin Impurity 1 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.
