Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,2,3-Trifluoro-4-iodobenzene (CAS 459424-72-7), molecular formula C6H2F3I and molecular weight 257.98 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to fluorine/iodine substitution, an aromatic ring system, 1,2,3-Trifluoro-4-iodobenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 257.98 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).
As a certified reference material (CRM), 1,2,3-Trifluoro-4-iodobenzene 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.
