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

2,6-Diethynylpyridine features two ethynyl groups positioned at the 2- and 6-positions of a pyridine ring, creating a rigid, electron-deficient scaffold ideal for conjugated systems. This arrangement enables efficient coupling in transition-metal-catalyzed reactions, delivering stable, planar architectures in organic semiconductors and coordination polymers.

Application

2,6-Diethynylpyridine serves as a versatile building block for constructing conjugated architectures and heterocyclic scaffolds. Its dual ethynyl groups enable efficient copper-catalyzed coupling reactions, facilitating the assembly of extended π-systems with high regiocontrol. The molecule exhibits excellent bench stability and compatibility with common functional groups, making it well-suited for modular synthesis in organic electronics and medicinal chemistry applications.
