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

1,4-Bis(phenylethynyl)benzene features two phenylethynyl groups attached to a para-substituted benzene core, creating a rigid, extended π-conjugated system. This structure enhances electronic delocalization, making it valuable in organic semiconductors and molecular electronics. The compound exhibits high thermal stability and is compatible with standard synthetic protocols.

Application

1,4-Bis(phenylethynyl)benzene serves as a robust building block for conjugated molecular architectures, enabling efficient access to extended π-systems via copper-catalyzed coupling reactions. Its dual alkyne functionalities exhibit high stability under standard handling conditions and tolerate diverse functional groups, facilitating straightforward purification and integration into advanced materials and heterocyclic frameworks.
