Chemical Structure
Description
As a certified reference material (CRM), 4-Bromo-2,2'-bithiophene 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 4-Bromo-2,2'-bithiophene (CAS 112051-56-6), a certified reference material (molecular formula C8H5BrS2, MW 245.16 g/mol) for analytical method development and quality control.
4-Bromo-2,2'-bithiophene (C8H5BrS2) contains sulfur-containing functionality, 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.
