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

6-Bromohex-1-yne is a halogenated alkyne featuring a terminal triple bond and a bromine atom at the C6 position. This structure enables selective coupling reactions in cross-coupling protocols, particularly in palladium-catalyzed transformations. The molecule exhibits good stability under standard conditions and facilitates efficient incorporation into complex molecular architectures.

Application

6-Bromohex-1-yne serves as a versatile building block in transition-metal-catalyzed coupling reactions, enabling efficient access to substituted alkynes and conjugated systems. Its terminal alkyne functionality reacts reliably with palladium and copper catalysts, while the bromide group supports cross-coupling protocols such as Stille, Suzuki-Miyaura, and Negishi reactions. The molecule exhibits good bench stability and is readily purified by distillation, facilitating integration into multi-step synthetic sequences for complex molecular architectures.
