Chemical Structure
Description
As a certified reference material (CRM), 2-Bromo-4-fluorothioanisole 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.
2-Bromo-4-fluorothioanisole (CAS 91524-70-8) is a high-purity analytical reference standard with the molecular formula C7H6BrFS and a molecular weight of 221.09 g/mol.
Owing to sulfur-containing functionality, fluorine/bromine substitution, an aromatic ring system, 2-Bromo-4-fluorothioanisole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 221.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
