4,5-Dibromo-2-(difluoromethoxy)benzenethiol CAS 1803789-16-3

Description

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system, 4,5-Dibromo-2-(difluoromethoxy)benzenethiol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 333.98 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

4,5-Dibromo-2-(difluoromethoxy)benzenethiol (CAS 1803789-16-3), molecular formula C7H4Br2F2OS and molecular weight 333.98 g/mol, is a CATO reference standard with documented purity and traceability.

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.
