1-(2,4-Dichlorobenzyl)-3-phenyl-1,5,6,7,8,9-hexahydroimidazo[1,2-a]azepin-4-ium bromide CAS 400856-69-1

Description

The occurrence of 1-(2,4-Dichlorobenzyl)-3-phenyl-1,5,6,7,8,9-hexahydroimidazo[1,2-a]azepin-4-ium bromide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(2,4-Dichlorobenzyl)-3-phenyl-1,5,6,7,8,9-hexahydroimidazo[1,2-a]azepin-4-ium bromide (CAS 400856-69-1), molecular formula C21H21Cl2N2BrH2O and molecular weight 470.23 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, 1-(2,4-Dichlorobenzyl)-3-phenyl-1,5,6,7,8,9-hexahydroimidazo[1,2-a]azepin-4-ium bromide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 470.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
