Chemical Structure

3,3-Dimethyl-3,4-dihydro-2H-[1,3'-biquinolin]-2-one CAS 918645-75-7 chemical structure

Description

3,3-Dimethyl-3,4-dihydro-2H-[1,3'-biquinolin]-2-one (CAS 918645-75-7), molecular formula C20H18N2O and molecular weight 302.37 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, 3,3-Dimethyl-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 302.37 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.

As a certified reference material (CRM), 3,3-Dimethyl-3,4-dihydro-2H-[1,3'-biquinolin]-2-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
