Description
CATO manufactures 4,8-Dichloro-3-ethyl-2-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.
4,8-Dichloro-3-ethyl-2-methylquinoline (CAS 1136-49-8) is a high-purity analytical reference standard with the molecular formula C12H11Cl2N and a molecular weight of 240.13 g/mol.
The molecular framework of 4,8-Dichloro-3-ethyl-2-methylquinoline (C12H11Cl2N) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
