Chemical Structure
Description
2-Chloro-4-(4-fluorophenyl)quinoline (CAS 105189-21-7), molecular formula C15H9ClFN and molecular weight 257.69 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Chloro-4-(4-fluorophenyl)quinoline (C15H9ClFN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 257.69 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 2-Chloro-4-(4-fluorophenyl)quinoline 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.
