Structurally, 5-(2-(3,5-Dichlorophenoxy)acetyl)-5,10-dihydro-11H-dibenzo[b,e][1,4]diazepin-11-one (C21H14Cl2N2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 413.25 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.
CATO supplies 5-(2-(3,5-Dichlorophenoxy)acetyl)-5,10-dihydro-11H-dibenzo[b,e][1,4]diazepin-11-one (CAS 866152-85-4), a certified reference material (molecular formula C21H14Cl2N2O3, MW 413.25 g/mol) for analytical method development and quality control.
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.
