Chemical Structure

2,4-Dichloro-3-methylquinoline CAS 56857-97-7 chemical structure

Description

The occurrence of 2,4-Dichloro-3-methylquinoline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2,4-Dichloro-3-methylquinoline (CAS 56857-97-7), a certified reference material (molecular formula C10H7Cl2N, MW 212.08 g/mol) for analytical method development and quality control.

The molecular framework of 2,4-Dichloro-3-methylquinoline (C10H7Cl2N) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

CATO manufactures 2,4-Dichloro-3-methylquinoline under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
