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-Bromo-2-chlorobenzene is a halogenated aromatic compound featuring adjacent bromo and chloro substituents on a benzene ring. This ortho-halogenated structure enables efficient cross-coupling reactions in palladium-catalyzed processes, offering high regioselectivity and stability under standard conditions. The molecule's electron-deficient character enhances reactivity in nucleophilic substitution pathways.

Application

1-Bromo-2-chlorobenzene serves as a versatile diaryl building block in cross-coupling reactions, enabling efficient construction of biaryl scaffolds under Pd-catalyzed conditions. Its ortho-halogen substitution pattern provides predictable regioselectivity in Suzuki, Stille, and Negishi couplings. The molecule exhibits good bench stability and compatibility with diverse functional groups, facilitating straightforward purification and integration into multi-step synthetic sequences for pharmaceutical and agrochemical intermediates.
