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.

Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

Tris(4-ethynylphenyl)amine features three ethynyl groups positioned at the para-positions of phenyl rings, enabling efficient copper-catalyzed azide-alkyne cycloaddition (CuAAC) for modular construction of complex architectures. This triarylamine scaffold offers enhanced electron-donating capacity and stability under standard conditions, making it ideal for integrating into conjugated systems, dendrimers, and functional materials where precise spatial control and high reactivity are required.

Application

Tris(4-ethynylphenyl)amine serves as a versatile triazine-based building block for copper-catalyzed azide-alkyne cycloaddition (CuAAC) and other click chemistry protocols. Its three terminal alkyne groups enable efficient construction of densely functionalized architectures, including dendrimers, conjugated polymers, and molecular scaffolds. The molecule exhibits excellent bench stability, facilitates straightforward purification, and demonstrates broad compatibility with common functional groups in synthetic workflows.
