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

1,4-Dibromo-2,3-dimethylbenzene features two bromine atoms positioned at para-adjacent sites on a benzene ring, flanked by methyl groups at the 2 and 3 positions. This sterically hindered architecture enhances stability under standard conditions while enabling selective coupling reactions in cross-coupling methodologies. The molecule integrates readily into complex aromatic frameworks via palladium-catalyzed transformations, delivering high functional group tolerance and predictable regiochemistry.

Application

1,4-Dibromo-2,3-dimethylbenzene serves as a versatile building block in aromatic synthesis, enabling palladium-catalyzed cross-coupling reactions due to its stable bromine substituents and defined substitution pattern. The dimethyl groups provide steric control and enhance solubility, while the molecule exhibits excellent bench stability and ease of purification—ideal for constructing complex arenes, heterocycles, and functionalized scaffolds in medicinal chemistry and materials science workflows.
