9-((Dimethylamino)methylene)-2-(4-fluorobenzylidene)-2,5,6,7,8,9-hexahydro-3H-imidazo[1,2-a]azepin-3-one CAS 730950-19-3 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 9-((Dimethylamino)methylene)-2-(4-fluorobenzylidene)-2,5,6,7,8,9-hexahydro-3H-imidazo[1,2-a]azepin-3-one (CAS 730950-19-3), a certified reference material (molecular formula C18H20FN3O, MW 313.37 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 9-((Dimethylamino)methylene)-2-(4-fluorobenzylidene)-2,5,6,7,8,9-hexahydro-3H-imidazo[1,2-a]azepin-3-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 313.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
