Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 446.44 g/mol gives Difamilast distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Difamilast (CAS 937782-05-3), molecular formula C23H24F2N2O5 and molecular weight 446.44 g/mol, is a CATO reference standard with documented purity and traceability.
Difamilast (C23H24F2N2O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Difamilast 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.
