Chemical Structure

6-(2,3-Dichlorophenyl)-6-oxohexanoic acid CAS 898791-13-4 chemical structure

Description

The occurrence of 6-(2,3-Dichlorophenyl)-6-oxohexanoic acid is closely related to a carboxylic acid group, 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.

6-(2,3-Dichlorophenyl)-6-oxohexanoic acid (CAS 898791-13-4), molecular formula C12H12Cl2O3 and molecular weight 275.13 g/mol, is a CATO reference standard with documented purity and traceability.

6-(2,3-Dichlorophenyl)-6-oxohexanoic acid (C12H12Cl2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, 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 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), 6-(2,3-Dichlorophenyl)-6-oxohexanoic 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.
