2-(3,4-Dichlorophenyl)-N-(4-methoxyphenyl)quinoline-4-carboxamide CAS 332175-88-9 chemical structure

Description

The occurrence of 2-(3,4-Dichlorophenyl)-N-(4-methoxyphenyl)quinoline-4-carboxamide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(3,4-Dichlorophenyl)-N-(4-methoxyphenyl)quinoline-4-carboxamide (CAS 332175-88-9) is a high-purity analytical reference standard with the molecular formula C23H16Cl2N2O2 and a molecular weight of 423.29 g/mol.

Structurally, 2-(3,4-Dichlorophenyl)-N-(4-methoxyphenyl)quinoline-4-carboxamide (C23H16Cl2N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 423.29 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.

As a certified reference material (CRM), 2-(3,4-Dichlorophenyl)-N-(4-methoxyphenyl)quinoline-4-carboxamide 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.
