Description
Compared with other compounds in its class, the molecular weight of 465.44 g/mol gives Xen 103 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Xen 103 (CAS 840489-44-3), molecular formula C22H23F4N5O2 and molecular weight 465.44 g/mol, is a CATO reference standard with documented purity and traceability.
Xen 103 (C22H23F4N5O2) contains a steroid 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 Xen 103 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.
