Chemical Structure
Description
3,4,6-Trichloro-2-hydroxybenzoic acid (CAS 68427-31-6), molecular formula C10H5F17O and molecular weight 464.12 g/mol, is a CATO reference standard with documented purity and traceability.
3,4,6-Trichloro-2-hydroxybenzoic acid (C10H5F17O) contains a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 3,4,6-Trichloro-2-hydroxybenzoic acid 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.
