Chemical Structure
Description
CATO supplies 1-Chloro-4-fluoro-2-iodo-5-methylbenzene (CAS 1639204-71-9), a certified reference material (molecular formula C7H5ClFI, MW 270.47 g/mol) for analytical method development and quality control.
1-Chloro-4-fluoro-2-iodo-5-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.
As a certified reference material (CRM), 1-Chloro-4-fluoro-2-iodo-5-methylbenzene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
