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-2-fluorobenzonitrile features a strategically positioned bromine and fluorine substituent on a benzene ring, enabling selective cross-coupling reactions. The nitrile group provides a polar handle for downstream functionalization, while the halogen atoms facilitate palladium-catalyzed transformations under standard conditions. This compound serves as a key intermediate in pharmaceutical synthesis.

Application

3-Bromo-2-fluorobenzonitrile serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling palladium-catalyzed cross-coupling reactions due to its well-established reactivity profile. The ortho-fluoro and bromo substituents provide complementary handles for sequential functionalization, while the nitrile group offers stability and utility in downstream transformations. Its bench-stable nature and compatibility with standard reaction conditions facilitate efficient access to complex heterocyclic scaffolds and substituted biaryls.
