Chemical Structure
Description
2,3-Dimethylphenyl 2-(4-bromophenyl)quinoline-4-carboxylate (CAS 355433-76-0) is a high-purity analytical reference standard with the molecular formula C24H18BrNO2 and a molecular weight of 432.31 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution, 2,3-Dimethylphenyl 2-(4-bromophenyl)quinoline-4-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 432.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 2,3-Dimethylphenyl 2-(4-bromophenyl)quinoline-4-carboxylate 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.
