Chemical Structure
Description
6,8-Dimethyl-2-(2-methylphenyl)quinoline-4-carbonyl chloride (CAS 1160254-89-6), molecular formula C19H16ClNO and molecular weight 309.79 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6,8-Dimethyl-2-(2-methylphenyl)quinoline-4-carbonyl chloride (C19H16ClNO) 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. 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 6,8-Dimethyl-2-(2-methylphenyl)quinoline-4-carbonyl chloride 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.
