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

5-Bromopent-1-yne is a versatile alkynyl halide featuring a terminal alkyne and pendant bromide. This molecule integrates readily into transition-metal-catalyzed coupling reactions, enabling efficient access to functionalized alkynes under standard conditions. The bromine atom serves as a robust electrophilic handle for further diversification.

Application

5-Bromopent-1-yne serves as a versatile building block in synthetic organic chemistry, enabling efficient access to functionalized alkynes through palladium-catalyzed coupling reactions. Its terminal alkyne and bromide functionalities allow for orthogonal transformations, facilitating the construction of complex scaffolds via Sonogashira, Stille, or Suzuki couplings. The compound exhibits good bench stability and is readily purified by distillation, making it well-suited for iterative synthesis workflows in medicinal chemistry and materials science.
