Chemical Structure
Description
4-chloro-7-fluoroquinoline (CAS 391-82-2) is a high-purity analytical reference standard with the molecular formula C9H15ClFN and a molecular weight of 191.67 g/mol.
Owing to a nitrile group, fluorine/chlorine substitution, 4-chloro-7-fluoroquinoline is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 191.67 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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-7-fluoroquinoline 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.
