Chemical Structure
Description
The occurrence of 1-Chloro-4,5-difluoro-2-iodobenzene is closely related to fluorine/chlorine/iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Chloro-4,5-difluoro-2-iodobenzene (CAS 1261629-20-2), molecular formula C6H2ClF2I and molecular weight 274.43 g/mol, is a CATO reference standard with documented purity and traceability.
1-Chloro-4,5-difluoro-2-iodobenzene (C6H2ClF2I) contains fluorine/chlorine/iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 1-Chloro-4,5-difluoro-2-iodobenzene 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.
