Chemical Structure
Description
The occurrence of 2,4-Dichlorophenylacetone is closely related to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,4-Dichlorophenylacetone (CAS 93457-07-9), molecular formula C9H8Cl2O and molecular weight 203.07 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C9H8Cl2O, 2,4-Dichlorophenylacetone contains a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 203.07 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 2,4-Dichlorophenylacetone 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.
