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

1,1,2,2-Tetrakis(4-ethynylphenyl)ethene is a tetraynyl-substituted ethene featuring four terminal alkyne groups. This highly functionalized scaffold enables efficient coupling in Sonogashira and click chemistry protocols. The extended π-conjugation supports applications in conjugated materials and molecular architectures requiring precise spatial control.

Application

1,1,2,2-Tetrakis(4-ethynylphenyl)ethene serves as a versatile tetrayne building block for the construction of conjugated π-systems and extended aromatic frameworks. Its four terminal alkyne groups enable efficient copper-catalyzed azide-alkyne cycloaddition (CuAAC) and Sonogashira coupling reactions, facilitating the assembly of complex molecular architectures. The molecule exhibits excellent bench stability and is readily purified by standard chromatographic methods, making it well-suited for iterative synthetic strategies in materials science and macrocyclic chemistry.
