Compared with other compounds in its class, the molecular weight of 303.39 g/mol gives 5-Benzyl-5,11-dihydro-10H-dibenzo[b,f]azepin-10-one-1,2,3,4-d4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Benzyl-5,11-dihydro-10H-dibenzo[b,f]azepin-10-one-1,2,3,4-d4 (CAS 1189446-39-6), molecular formula C21H13D4NO and molecular weight 303.39 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage, 5-Benzyl-5,11-dihydro-10H-dibenzo[b,f]azepin-10-one-1,2,3,4-d4 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 303.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
