Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 269.12 g/mol gives Dichlorophen distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Dichlorophen (CAS 97-23-4), a certified reference material (molecular formula C13H10Cl2O2, MW 269.12 g/mol) for analytical method development and quality control.
Dichlorophen (C13H10Cl2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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), Dichlorophen 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.
