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

4,4'-Diethynyl-1,1'-biphenyl features a rigid biphenyl scaffold with terminal ethynyl groups enabling efficient coupling in Sonogashira and Glaser-type reactions. This structure facilitates the construction of conjugated oligomers and functionalized carbon nanomaterials under mild conditions.

Application

4,4'-Diethynyl-1,1'-biphenyl serves as a versatile building block for conjugated molecular architectures, enabling efficient Sonogashira coupling and cyclization reactions. Its dual ethynyl groups exhibit high stability under standard handling conditions and facilitate the construction of extended π-systems, including fused heterocycles and macrocyclic frameworks. The molecule demonstrates excellent functional group tolerance and is readily purified by column chromatography, making it well-suited for iterative synthetic sequences in materials science and target-oriented synthesis.
