Chemical Structure
Description
(E)-2-Iodoethenyltrimethylsilane (CAS 70737-22-3), molecular formula C5H11ISi and molecular weight 226.13 g/mol, is a CATO reference standard with documented purity and traceability.
(E)-2-Iodoethenyltrimethylsilane (C5H11ISi) contains 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.
CATO manufactures (E)-2-Iodoethenyltrimethylsilane under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
