Chemical Structure

2,5-Dichloro-3-fluorobenzoyl chloride CAS 1803718-66-2 chemical structure

Description

The occurrence of 2,5-Dichloro-3-fluorobenzoyl chloride is closely related to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2,5-Dichloro-3-fluorobenzoyl chloride (CAS 1803718-66-2), molecular formula C7H2Cl3FO and molecular weight 227.45 g/mol, is a CATO reference standard with documented purity and traceability.

2,5-Dichloro-3-fluorobenzoyl chloride (C7H2Cl3FO) contains a hydroxyl group, an ether linkage, fluorine/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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 2,5-Dichloro-3-fluorobenzoyl 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.
