Chemical Structure
Description
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.
CATO supplies Phenazepam-D4 (CAS 1184980-42-4), a certified reference material (molecular formula C15H6D4BrClN2O, MW 353.63 g/mol) for analytical method development and quality control.
Structurally, Phenazepam-D4 (C15H6D4BrClN2O) contains deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine 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 353.63 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
