4,5-Dichloro-2,8-dimethylquinoline CAS 21629-52-7

Description

The occurrence of 4,5-Dichloro-2,8-dimethylquinoline 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 4,5-Dichloro-2,8-dimethylquinoline (CAS 21629-52-7), a certified reference material (molecular formula C11H9Cl2N, MW 226.10 g/mol) for analytical method development and quality control.

4,5-Dichloro-2,8-dimethylquinoline (C11H9Cl2N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 4,5-Dichloro-2,8-dimethylquinoline 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.
