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

2-Bromo-3-chlorobenzonitrile features a nitrile group flanked by bromo and chloro substituents at adjacent ortho positions, enabling selective coupling in cross-coupling reactions. This electron-deficient aromatic scaffold offers enhanced reactivity in palladium-catalyzed transformations while maintaining stability under standard conditions.

Application

2-Bromo-3-chlorobenzonitrile serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling palladium-catalyzed cross-coupling reactions due to its orthogonal halogen reactivity. The nitrile group provides a handle for downstream functionalization, while the bromo and chloro substituents offer complementary reactivity in sequential coupling strategies. Bench-stable and readily purified by column chromatography, it functions effectively in Suzuki, Stille, and Negishi transformations under standard conditions.
