Chemical Structure
Description
CATO supplies 1-CHLORO-2-FLUORO-3-IODO-4-METHOXYBENZENE (CAS 1402004-77-6), a certified reference material (molecular formula C7H5ClFIO, MW 286.47 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, fluorine/chlorine/iodine substitution, an aromatic ring system, 1-CHLORO-2-FLUORO-3-IODO-4-METHOXYBENZENE is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 286.47 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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-2-FLUORO-3-IODO-4-METHOXYBENZENE 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.
