Description
As a certified reference material (CRM), 1-(1-Iodoethenyl)-4-methylbenzene 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 1-(1-Iodoethenyl)-4-methylbenzene (CAS 359887-53-9), a certified reference material (molecular formula C9H9I, MW 244.07 g/mol) for analytical method development and quality control.
Based on its molecular formula C9H9I, 1-(1-Iodoethenyl)-4-methylbenzene contains iodine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 244.07 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
