HazMat Fee

An item is classified as a dangerous good if our website displays Hazardous Material (HazMat) information for it. There is a HazMat shipping fee for each item that qualifies as a dangerous good, except in the following scenarios:

The shipment is processed through FedEx Ground under the Limited Quantity option.

Each bottle is packed as an Excepted Quantity, with a maximum of 1g for items in class 6.1 packing group I or II, and up to 25g for all other hazardous materials.

If shipping is charged to your FedEx account, the HazMat fee will be billed directly by the courier. Otherwise, the fee will be included on your invoice. To help you avoid the HazMat fee, we can package a 5g order of a class 6.1 packing group I or II material as five separate 1g units, and a 100g order of any other dangerous good as four 25g units. This packaging adjustment will be made unless you instruct otherwise on your purchase order. Below, you will find the fee schedule from FedEx for handling hazardous materials.

Description

4-Bromo-3,5-dimethylphenylboronic acid features a sterically hindered boronic acid group flanked by two methyl substituents and a bromine atom, enabling selective cross-coupling in Suzuki-Miyaura reactions. The electron-rich aromatic core enhances reactivity under mild conditions, while the bench-stable nature simplifies handling and storage. This structure facilitates efficient incorporation into complex molecular architectures.

Application

4-Bromo-3,5-dimethylphenylboronic acid serves as a versatile building block in Suzuki-Miyaura coupling reactions, enabling efficient C–C bond formation under mild conditions. Its ortho-dimethyl substitution enhances bench stability and reduces protodeboronation, while the bromine handle permits downstream functionalization via cross-coupling or palladium-catalyzed transformations. Ideal for constructing substituted biaryls and heterocyclic scaffolds in medicinal chemistry and materials science.
