(5aR,6S,9S,9aS)-2-Mesityl-6,11,11-trimethyl-5a,6,7,8,9,9a-hexahydro-4H-6,9-methanobenzo[b][1,2,4]triazolo[4,3-d][1,4]oxazin-2-ium Tetrafluoroborate (CAS 1037287-79-8), molecular formula C21H28N3OBF4 and molecular weight 425.28 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, (5aR,6S,9S,9aS)-2-Mesityl-6,11,11-trimethyl-5a,6,7,8,9,9a-hexahydro-4H-6,9-methanobenzo[b][1,2,4]triazolo[4,3-d][1,4]oxazin-2-ium Tetrafluoroborate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 425.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
