Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 372.33 g/mol gives 1,3,5-Tri-tert-butyl-2-iodobenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,3,5-Tri-tert-butyl-2-iodobenzene (CAS 31039-82-4), molecular formula C18H29I and molecular weight 372.33 g/mol, is a CATO reference standard with documented purity and traceability.
1,3,5-Tri-tert-butyl-2-iodobenzene (C18H29I) contains iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 1,3,5-Tri-tert-butyl-2-iodobenzene 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.
