Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 223.48 g/mol gives 1-(3,4,5-Trichlorophenyl)ethanone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-(3,4,5-Trichlorophenyl)ethanone (CAS 35981-65-8), molecular formula C8H5Cl3O and molecular weight 223.48 g/mol, is a CATO reference standard with documented purity and traceability.
1-(3,4,5-Trichlorophenyl)ethanone (C8H5Cl3O) contains a hydroxyl group, an ether linkage, chlorine 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).
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), 1-(3,4,5-Trichlorophenyl)ethanone 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.
