Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(S)-SW IV-52 (trifluoroacetate) (CAS 762274-49-7), molecular formula C25H38N4O3C2HF3O2 and molecular weight 556.63 g/mol, is a CATO reference standard with documented purity and traceability.
(S)-SW IV-52 (trifluoroacetate) (C25H38N4O3C2HF3O2) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures (S)-SW IV-52 (trifluoroacetate) 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.
