3-(11-Chloro-2,3-dihydrodiimidazo[1,5-a:1',2'-c]quinazolin-5-yl)-5-cyclopropyl-1,2,4-oxadiazole (CAS 134516-99-7), molecular formula C17H13ClN6O and molecular weight 352.78 g/mol, is a CATO reference standard with documented purity and traceability.

3-(11-Chloro-2,3-dihydrodiimidazo[1,5-a:1',2'-c]quinazolin-5-yl)-5-cyclopropyl-1,2,4-oxadiazole (C17H13ClN6O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; 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.

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.

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.
