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

3-Bromo-5-fluorophenol features a phenolic hydroxyl group flanked by bromo and fluoro substituents at meta positions, enabling selective coupling reactions in medicinal chemistry. This electron-deficient aromatic scaffold supports efficient transition-metal-catalyzed transformations and serves as a key building block for bioactive heterocycles and functionalized aryl ethers under standard conditions.

Application

3-Bromo-5-fluorophenol serves as a valuable building block in medicinal chemistry and agrochemical synthesis, enabling direct functionalization at the ortho-position relative to hydroxyl. Its bromine and fluorine substituents provide orthogonal reactivity for palladium-catalyzed cross-coupling and electrophilic substitution, respectively. The compound exhibits excellent bench stability, facilitates straightforward purification via recrystallization, and functions reliably in Suzuki-Miyaura, Stille, and Sonogashira reactions.
