Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 288.93 g/mol gives 3-Bromo-2-iodothiophene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Bromo-2-iodothiophene (CAS 60404-24-2), molecular formula C4H2BrIS and molecular weight 288.93 g/mol, is a CATO reference standard with documented purity and traceability.
3-Bromo-2-iodothiophene (C4H2BrIS) contains sulfur-containing functionality, bromine/iodine substitution. 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.
As a certified reference material (CRM), 3-Bromo-2-iodothiophene 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.
