Description

As a certified reference material (CRM), 4,4,8-Trimethyl-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.

CATO supplies 4,4,8-Trimethyl-3,4-dihydro-2H-[1,3'-biquinolin]-2-one (CAS 918646-32-9), a certified reference material (molecular formula C21H20N2O, MW 316.40 g/mol) for analytical method development and quality control.

Structurally, 4,4,8-Trimethyl-3,4-dihydro-2H-[1,3'-biquinolin]-2-one (C21H20N2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 316.40 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
