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

4-Methylpyridine-2,6-dicarbonitrile features a pyridine core with two nitrile groups at the 2 and 6 positions and a methyl substituent at the 4 position. This electron-deficient heterocycle integrates readily into modular synthesis pathways, offering high stability under standard conditions. The strategic placement of functional groups enables efficient coupling in transition metal-catalyzed reactions and facilitates incorporation into advanced ligands and pharmaceutical intermediates.

Application

4-Methylpyridine-2,6-dicarbonitrile serves as a versatile building block in synthetic organic chemistry, enabling the construction of functionalized heterocyclic scaffolds through established coupling and cyclization protocols. Its dual nitrile groups and methyl-substituted pyridine core provide high reactivity in nucleophilic substitution and transition-metal-catalyzed transformations, offering excellent functional group tolerance and bench stability for use in medicinal chemistry and materials science applications.
