8-chloro-4-(dimethylaminomethylene)-1-(2-fluoro-6-methoxy-phenyl)-3H-2-benzazepin-5-one CAS 869367-33-9

Description

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.

8-chloro-4-(dimethylaminomethylene)-1-(2-fluoro-6-methoxy-phenyl)-3H-2-benzazepin-5-one (CAS 869367-33-9), molecular formula C20H30ClFN2O2 and molecular weight 384.92 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, fluorine/chlorine substitution, 8-chloro-4-(dimethylaminomethylene)-1-(2-fluoro-6-methoxy-phenyl)-3H-2-benzazepin-5-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 384.92 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
