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-1-chloro-2-methylbenzene features a strategically positioned bromo and chloro substituent on a methylated benzene ring, enabling selective cross-coupling reactions. The ortho-methyl group enhances regioselectivity in palladium-catalyzed transformations, while the halogen array supports sequential functionalization under mild conditions. This electron-deficient aryl scaffold delivers high reactivity with minimal side-product formation.

Application

4-Bromo-1-chloro-2-methylbenzene serves as a versatile building block in cross-coupling reactions, enabling efficient construction of biaryl and heteroaryl scaffolds. Its orthogonal halogen reactivity—bromine undergoing palladium-catalyzed coupling while chloride remains inert—facilitates sequential functionalization. The methyl group provides a site for further oxidation or directed metallation, enhancing synthetic versatility. Bench-stable and readily purified by distillation, it supports scalable synthesis in medicinal chemistry and materials development.
