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-chloro-6-methylnicotinonitrile features a trifunctional pyridine core with complementary reactivity at the bromo, chloro, and nitrile positions. This electron-deficient scaffold enables selective cross-coupling and nucleophilic substitution under mild conditions, offering efficient access to complex heterocyclic architectures in medicinal chemistry and materials synthesis.

Application

5-Bromo-2-chloro-6-methylnicotinonitrile serves as a versatile building block in medicinal chemistry, enabling the construction of substituted pyridine scaffolds via palladium-catalyzed cross-coupling reactions. The molecule’s orthogonal halogenation pattern—bromine at C5 and chlorine at C2—allows for sequential functionalization with high chemoselectivity. The nitrile group provides a handle for downstream transformations, including hydrolysis to carboxylic acids or reduction to aldehydes. Bench-stable and readily purified by column chromatography, it facilitates efficient synthesis of complex heterocyclic intermediates.
