Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 303.53 g/mol gives 4-Chloro-3-iodo-2-methylquinoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Chloro-3-iodo-2-methylquinoline (CAS 1033931-93-9), molecular formula C10H7ClIN and molecular weight 303.53 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Chloro-3-iodo-2-methylquinoline (C10H7ClIN) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/iodine 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-Chloro-3-iodo-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.
