Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 374.41 g/mol gives 3-chloro-2,5-diiodo-thiophene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-chloro-2,5-diiodo-thiophene (CAS 2250242-07-8), a certified reference material (molecular formula C4H5ClI2S, MW 374.41 g/mol) for analytical method development and quality control.
3-chloro-2,5-diiodo-thiophene (C4H5ClI2S) contains sulfur-containing functionality, chlorine/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-chloro-2,5-diiodo-thiophene 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.
