7-Chloro-3,8-dimethyl-2-phenylquinoline-4-carboxylic acid CAS 862647-93-6

Description

The occurrence of 7-Chloro-3,8-dimethyl-2-phenylquinoline-4-carboxylic acid 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.

CATO supplies 7-Chloro-3,8-dimethyl-2-phenylquinoline-4-carboxylic acid (CAS 862647-93-6), a certified reference material (molecular formula C18H14ClNO2, MW 311.76 g/mol) for analytical method development and quality control.

The molecular framework of 7-Chloro-3,8-dimethyl-2-phenylquinoline-4-carboxylic acid (C18H14ClNO2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
