Description
CATO supplies 1-Iodo-2-[(methylthio)methyl]-benzene (CAS 117760-02-8), a certified reference material (molecular formula C8H9IS, MW 264.13 g/mol) for analytical method development and quality control.
Structurally, 1-Iodo-2-[(methylthio)methyl]-benzene (C8H9IS) contains sulfur-containing functionality, iodine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 264.13 g/mol, it falls into the medium-molecular-weight range. 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), 1-Iodo-2-[(methylthio)methyl]-benzene 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.
