Chemical Structure

7-Fluoro-3,3,4,4-tetramethyl-3,4-dihydro-2H-[1,3'-biquinolin]-2-one CAS 918646-12-5 chemical structure

Description

The occurrence of 7-Fluoro-3,3,4,4-tetramethyl-3,4-dihydro-2H-[1,3'-biquinolin]-2-one is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 7-Fluoro-3,3,4,4-tetramethyl-3,4-dihydro-2H-[1,3'-biquinolin]-2-one (CAS 918646-12-5), a certified reference material (molecular formula C22H21FN2O, MW 348.41 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, 7-Fluoro-3,3,4,4-tetramethyl-3,4-dihydro-2H-[1,3'-biquinolin]-2-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 348.41 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.

CATO manufactures 7-Fluoro-3,3,4,4-tetramethyl-3,4-dihydro-2H-[1,3'-biquinolin]-2-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
