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

5-Bromo-2-chlorophenol delivers a dual halogenated aromatic scaffold with enhanced reactivity for cross-coupling and functionalization. The ortho-chloro group enables selective metalation, while the bromo substituent serves as a robust handle for palladium-catalyzed transformations. This bench-stable phenolic derivative integrates readily into complex molecular architectures under standard conditions.

Application

5-Bromo-2-chlorophenol serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling regioselective functionalization via palladium-catalyzed cross-coupling reactions. Its ortho-halogenated phenolic structure provides excellent compatibility with standard Suzuki, Stille, and Negishi coupling protocols, while the hydroxyl group allows for direct derivatization or protection. Bench-stable and readily purified by recrystallization, it functions as a key intermediate in the construction of bioactive heterocycles and substituted aromatic scaffolds.
