Chemical Structure
Description
The occurrence of 1-chloro-4-fluoro-5-iodo-2-methylbenzene 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-fluoro-5-iodo-2-methylbenzene (CAS 1263275-80-4) is a high-purity analytical reference standard with the molecular formula C7H5ClFI and a molecular weight of 270.47 g/mol.
1-chloro-4-fluoro-5-iodo-2-methylbenzene (C7H5ClFI) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
