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

2,4-Dibromo-1-methylbenzene features a methyl-substituted aromatic core with bromine atoms at the 2 and 4 positions, enabling selective cross-coupling reactions. The electron-deficient aryl framework supports palladium-catalyzed transformations, while the bench-stable structure simplifies handling in synthetic workflows.

Application

2,4-Dibromo-1-methylbenzene serves as a versatile building block for palladium-catalyzed cross-coupling reactions, enabling efficient synthesis of substituted biaryls and functionalized arenes. The methyl group provides a handle for further oxidation or functionalization, while the ortho-bromine positions offer high reactivity in Suzuki, Stille, and Negishi couplings. Bench-stable and readily purified by column chromatography, it facilitates scalable access to complex aromatic scaffolds in medicinal chemistry and materials science applications.
