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-5-methylbenzonitrile features a strategically positioned bromine atom and nitrile group on a methyl-substituted benzene ring, enabling direct functionalization in cross-coupling reactions. The electron-withdrawing nitrile enhances reactivity at the ortho-brominated site, while the methyl group provides steric and electronic modulation. This compound serves as a key intermediate in pharmaceutical and agrochemical synthesis, offering predictable regioselectivity under standard conditions.

Application

2-Bromo-5-methylbenzonitrile serves as a versatile building block in synthetic organic chemistry, enabling palladium-catalyzed cross-coupling reactions due to its stable aryl bromide and nitrile functionalities. The methyl group provides ortho-directing capability for electrophilic substitution, while the nitrile group offers compatibility with subsequent transformations such as hydrolysis or reduction. Bench-stable and readily purified by recrystallization, it functions efficiently in the construction of heterocyclic scaffolds and functionalized biaryls common in medicinal chemistry research.
