Chemical Structure
Description
CATO supplies 4-Bromo-2-(difluoromethoxy)thioanisole (CAS 1807244-72-9), a certified reference material (molecular formula C8H7BrF2OS, MW 269.11 g/mol) for analytical method development and quality control.
The molecular framework of 4-Bromo-2-(difluoromethoxy)thioanisole (C8H7BrF2OS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 4-Bromo-2-(difluoromethoxy)thioanisole 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.
