Chemical Structure
Description
As a certified reference material (CRM), 2-(Difluoromethyl)-5-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.
2-(Difluoromethyl)-5-iodothiophene (CAS 2092628-46-9), molecular formula C5H3F2IS and molecular weight 260.04 g/mol, is a CATO reference standard with documented purity and traceability.
2-(Difluoromethyl)-5-iodothiophene (C5H3F2IS) contains sulfur-containing functionality, fluorine/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.
