(5aS,6R,9S,9aR)-5a,6,7,8,9,9a-Hexahydro-6,11,11-trimethyl-2-(2,3,4,5,6-pentafluorophenyl)-6,9-methano-4H-[1,2,4]triazolo[3,4-c][1,4]benzoxazinium tetrafluoroborate (CAS 1037287-81-2), molecular formula C19H19F5N3OBF4 and molecular weight 487.17 g/mol, is a CATO reference standard with documented purity and traceability.
(5aS,6R,9S,9aR)-5a,6,7,8,9,9a-Hexahydro-6,11,11-trimethyl-2-(2,3,4,5,6-pentafluorophenyl)-6,9-methano-4H-[1,2,4]triazolo[3,4-c][1,4]benzoxazinium tetrafluoroborate (C19H19F5N3OBF4) 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), (5aS,6R,9S,9aR)-5a,6,7,8,9,9a-Hexahydro-6,11,11-trimethyl-2-(2,3,4,5,6-pentafluorophenyl)-6,9-methano-4H-[1,2,4]triazolo[3,4-c][1,4]benzoxazinium tetrafluoroborate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
