Application

Potassium p-tolyltrifluoroborate can be used:
  • As a precursor/starting material for the synthesis of biaryl compounds by reacting with various aryl halides using Pd/C catalyst.
  • As a reagent in the carbonylative arylation of vinyl ketones via 1,4-addition.
  • As a substrate in the synthesis of primary arylamines by reacting with hydroxylamine-O-sulfonic acid under metal-free conditions.

Stabilized 2-Iodoxybenzoic Acid (SIBX)

IBX is not often used due to the fact that it is an impact-sensitive explosive material, which prevents its shipping and transport, as well as its application in industry.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
