Chemical Structure
Description
The occurrence of 苯并氮杂卓并环衍生物类中间体亚硝胺杂质6 is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
苯并氮杂卓并环衍生物类中间体亚硝胺杂质6 (CAS CATO-C3D-262678) is a certified pharmaceutical impurity reference standard with the molecular formula C17H22ClN3O3 and a molecular weight of 351.83 g/mol.
The molecular framework of 苯并氮杂卓并环衍生物类中间体亚硝胺杂质6 (C17H22ClN3O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
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.
