    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-Ethynyl-4-nitrobenzene features a terminal alkyne coupled to a para-nitro aromatic ring, enabling efficient copper-catalyzed coupling reactions. The electron-deficient aryl group enhances reactivity in click chemistry applications, while the acetylenic functionality offers robust compatibility with palladium and nickel catalysis. This compound delivers precise structural integration in conjugated systems and functional materials.

Application

1-Ethynyl-4-nitrobenzene serves as a versatile building block in transition-metal-catalyzed coupling reactions, enabling efficient access to conjugated enynes and extended π-systems. The nitro group enhances regioselectivity in Sonogashira couplings, while the terminal alkyne offers high functional group tolerance and compatibility with standard purification methods. Its bench-stable nature and predictable reactivity make it ideal for constructing complex molecular architectures in medicinal chemistry and materials science applications.
