Chemical Structure

2,5-Difluoroanisole CAS 75626-17-4 chemical structure

Description

As a certified reference material (CRM), 2,5-Difluoroanisole 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.

CATO supplies 2,5-Difluoroanisole (CAS 75626-17-4), a certified reference material (molecular formula C7H6F2O, MW 144.12 g/mol) for analytical method development and quality control.

2,5-Difluoroanisole (C7H6F2O) contains a hydroxyl group, an ether linkage, fluorine 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.
