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

3-Ethynyl-1,1'-biphenyl features a terminal alkyne group flanked by two aromatic rings, enabling efficient copper-catalyzed coupling reactions. This rigid, electron-rich scaffold integrates readily into conjugated systems, offering enhanced stability and predictable reactivity in synthetic workflows.

Application

3-Ethynyl-1,1'-biphenyl serves as a versatile building block in transition-metal-catalyzed coupling reactions, enabling efficient access to conjugated biaryl architectures. Its terminal alkyne functionality facilitates reliable Sonogashira and Glaser-type couplings, while the biphenyl core provides structural rigidity and π-conjugation. The compound exhibits excellent bench stability and is readily purified by standard chromatographic methods, making it well-suited for iterative synthetic sequences in medicinal chemistry and materials science applications.
