Chemical Structure
Description
Structurally, 1-(3,5-dichlorophenyl)-5-methyl-N-(2-morpholinophenyl)-1H-1,2,4-triazole-3-carboxamide (C20H19Cl2N5O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 432.30 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
1-(3,5-dichlorophenyl)-5-methyl-N-(2-morpholinophenyl)-1H-1,2,4-triazole-3-carboxamide (CAS 400080-92-4), molecular formula C20H19Cl2N5O2 and molecular weight 432.30 g/mol, is a CATO reference standard with documented purity and traceability.
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.
