    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-Diiodobutane serves as a versatile dihalide linker for constructing cyclic and acyclic frameworks in synthetic organic chemistry. This linear alkyl diiodide features reactive C–I bonds that facilitate efficient coupling reactions, including cross-coupling and cyclization processes. The molecule exhibits high stability under standard conditions and enables precise spatial control in molecular design.

Application

1,4-Diiodobutane serves as a versatile dihalide building block for the synthesis of cyclic and acyclic compounds via double alkylation or transition-metal-catalyzed coupling reactions. Its well-defined reactivity enables efficient construction of 1,4-difunctionalized scaffolds, including heterocycles and macrocyclic frameworks. The compound exhibits good bench stability and facilitates clean functional group transformations with minimal side-product formation, making it suitable for scalable synthetic applications in medicinal chemistry and materials science.
