Chemical Structure
Description
3,4-Dichloro-N-[2,4-dichloro-5-(propan-2-yloxy)phenyl]benzamide (CAS 338961-14-1), molecular formula C16H13Cl4NO2 and molecular weight 393.09 g/mol, is a CATO reference standard with documented purity and traceability.
3,4-Dichloro-N-[2,4-dichloro-5-(propan-2-yloxy)phenyl]benzamide (C16H13Cl4NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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-Dichloro-N-[2,4-dichloro-5-(propan-2-yloxy)phenyl]benzamide 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.
