(5-Chloro-2-(3-((diethylamino)methyl)-5-methyl-4H-1,2,4-triazol-4-yl)phenyl)(phenyl)methanone (CAS 38150-34-4), molecular formula C21H23ClN4O and molecular weight 382.89 g/mol, is a CATO reference standard with documented purity and traceability.
(5-Chloro-2-(3-((diethylamino)methyl)-5-methyl-4H-1,2,4-triazol-4-yl)phenyl)(phenyl)methanone (C21H23ClN4O) 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.
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.
