Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 258.57 g/mol gives 3-(Pentafluorophenyl)propionyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-(Pentafluorophenyl)propionyl chloride (CAS 2063-40-3), a certified reference material (molecular formula C9H4ClF5O, MW 258.57 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, 3-(Pentafluorophenyl)propionyl chloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 258.57 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 3-(Pentafluorophenyl)propionyl 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.
