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

6-Amino-5-chloro-3-pyridinecarbonitrile features a pyridine core functionalized with electron-withdrawing nitrile and chloro groups flanking a primary amine, enabling direct incorporation into heterocyclic scaffolds. This bench-stable derivative serves as a key intermediate in medicinal chemistry, particularly for kinase inhibitor and antiviral agent development.

Application

6-Amino-5-chloro-3-pyridinecarbonitrile serves as a versatile building block in medicinal chemistry, enabling the construction of pyridine-based heterocycles through standard coupling and functional group transformation protocols. Its ortho-substituted nitrile and amino groups provide complementary reactivity for late-stage derivatization, while the chlorine atom facilitates palladium-catalyzed cross-coupling reactions. The compound exhibits good bench stability and is readily purified by recrystallization or chromatography, supporting its use in scalable synthesis workflows.
