Chemical Structure
Description
Tris(4-iodo-2,3,5,6-tetramethylphenyl)borane (CAS 321735-69-7) is a high-purity analytical reference standard with the molecular formula C30H36BI3 and a molecular weight of 788.13 g/mol.
Owing to iodine substitution, a polycyclic aromatic system, Tris(4-iodo-2,3,5,6-tetramethylphenyl)borane is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 788.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 Tris(4-iodo-2,3,5,6-tetramethylphenyl)borane 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.
