Description
CATO supplies 2-(2,5-Dichlorophenyl)acetyl chloride (CAS 203314-48-1), a certified reference material (molecular formula C8H5Cl3O, MW 223.48 g/mol) for analytical method development and quality control.
2-(2,5-Dichlorophenyl)acetyl chloride (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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 2-(2,5-Dichlorophenyl)acetyl chloride 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.
