Chemical Structure
Description
(5S)-5,6-Dihydro-2-(2,3,4,5,6-pentafluorophenyl)-5-(phenylmethyl)-8H-1,2,4-triazolo[3,4-c][1,4]oxazinium tetrafluoroborate (C18H13F5N3OBF3F) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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).
CATO supplies (5S)-5,6-Dihydro-2-(2,3,4,5,6-pentafluorophenyl)-5-(phenylmethyl)-8H-1,2,4-triazolo[3,4-c][1,4]oxazinium tetrafluoroborate (CAS 1327274-33-8), a certified reference material (molecular formula C18H13F5N3OBF3F, MW 469.11 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
