Chemical Structure
Description
The occurrence of 4,8-Dichloro-2,7-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 4,8-Dichloro-2,7-dimethylquinoline (CAS 288151-53-1), a certified reference material (molecular formula C11H9Cl2N, MW 226.10 g/mol) for analytical method development and quality control.
The molecular framework of 4,8-Dichloro-2,7-dimethylquinoline (C11H9Cl2N) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4,8-Dichloro-2,7-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.
