    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-Iodobut-1-yne is a reactive alkyne reagent featuring a terminal triple bond and a pendant iodide. This configuration enables efficient copper-catalyzed coupling reactions, particularly in click chemistry applications. The molecule exhibits high stability under standard conditions and facilitates rapid conjugation with azide-functionalized partners, streamlining the synthesis of bioconjugates and functionalized polymers.

Application

4-Iodobut-1-yne serves as a versatile building block in transition-metal-catalyzed coupling reactions, enabling efficient access to conjugated alkyne architectures. Its terminal alkyne functionality facilitates Sonogashira and Glaser couplings, while the iodide group provides a reliable handle for palladium-catalyzed cross-coupling transformations. The compound exhibits good bench stability and is compatible with standard purification protocols, making it a practical choice for synthesizing complex molecular scaffolds in medicinal chemistry and materials science applications.
