3,5-Dimethylphenylboronic acid (DMPBA) can be used as:
A reactant in the palladium-catalyzed Suzuki coupling reactions.
A co-extractant in the combination with modified Aliquat 336 for the extraction of xylose, glucose, and fructose from aqueous solutions.
A reactant to prepare penultimate methyl ester.
3,5-Dimethylphenylboronic acid (CAS: 109467-89-4) is a specialized organic intermediate synthesized via lithium-halogen exchange or direct borylation of m-xylene derivatives. Its molecular formula is C8H11BO2. This compound serves as a critical coupling partner in Suzuki-Miyaura cross-coupling reactions for constructing complex biaryl scaffolds.
Store in a cool, dry, inert atmosphere to prevent hydrolysis. Avoid inhalation of dust; wear appropriate PPE including goggles and nitrile gloves. Do not use in food additives or unregulated clinical trials without rigorous purity validation.
