2-Bromo-4-(difluoromethoxy)thioanisole CAS 1804409-43-5

Description

As a certified reference material (CRM), 2-Bromo-4-(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.

2-Bromo-4-(difluoromethoxy)thioanisole (CAS 1804409-43-5) is a high-purity analytical reference standard with the molecular formula C8H7BrF2OS and a molecular weight of 269.11 g/mol.

2-Bromo-4-(difluoromethoxy)thioanisole (C8H7BrF2OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/bromine 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.
