3,4-DIMETHYLBENZENEBORONIC ACID - Introduction

3,4-Dimethylphenylboronic acid is an organic boron compound with the chemical formula C8H11BO2. In its structure, there is a methyl group on the 3 and 4 positions of the benzene ring. The compound is a white crystal or powder.

3,4-Dimethylphenylboronic acid is mainly used as organic boron reagent in organic synthesis reaction. It can react with allyl alcohol, aldehyde, ketone, acid, etc. to generate C- C bonds, which are used to synthesize natural products, drugs, pesticides and other organic molecules. It can also be used as a ligand to form complexes with metal ions for catalytic reactions.

The common method for preparing 3,4-Dimethylphenylboronic acid is through the condensation reaction between phenylboronic acid and p-methylphenol. The reaction conditions are usually room temperature, a certain time of reaction, after the product is obtained by crystallization purification to obtain pure product.

Regarding safety information, 3,4-Dimethylphenylboronic acid is not particularly dangerous. However, as with all chemicals, care should be taken for proper handling and storage. Avoid inhalation, swallowing, or contact with skin and eyes. Wear appropriate protective equipment, such as gloves and glasses.
