(3,5-Di-tert-butylphenyl)boronic acid（Cat No.:R073155）is a white to off-white crystalline powder featuring a phenyl ring substituted with bulky tert-butyl groups at the 3 and 5 positions and a boronic acid group. This sterically hindered boronic acid is commonly used in Suzuki-Miyaura cross-coupling reactions for forming carbon-carbon bonds in organic synthesis, particularly in pharmaceuticals and advanced materials. The tert-butyl groups enhance solubility and influence the electronic and steric properties of reaction intermediates. It should be stored in a cool, dry place and handled with standard precautions to avoid moisture and degradation.
