Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-Fluoro-5-iodo-2-methylphenol (CAS 900175-53-3), molecular formula C7H6FIO and molecular weight 252.02 g/mol, is a CATO reference standard with documented purity and traceability.
4-Fluoro-5-iodo-2-methylphenol (C7H6FIO) contains a hydroxyl group, an ether linkage, fluorine/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).
As a certified reference material (CRM), 4-Fluoro-5-iodo-2-methylphenol 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.
