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.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+
Inaccessible (Haz class 6.1 or 9), International	$108.00+
Accessible (Haz class 3, 4, 5 or 8), International	$238.00+

Description

1-(But-3-yn-1-yl)piperazine features a terminal alkyne group appended to a piperazine core, enabling facile copper-catalyzed azide-alkyne cycloaddition (CuAAC) for bioconjugation and materials assembly. The alkyne moiety offers high reactivity under mild conditions, while the piperazine nitrogen atoms provide solubility and versatility in synthetic transformations. This scaffold integrates readily into functionalized probes, polymers, and pharmaceutical intermediates.

Application

1-(But-3-yn-1-yl)piperazine serves as a versatile building block in medicinal chemistry, enabling efficient access to diverse heterocyclic scaffolds via copper-catalyzed azide-alkyne cycloaddition (CuAAC). Its terminal alkyne functionality offers high reactivity and compatibility with standard click chemistry protocols, while the piperazine moiety provides favorable solubility and metabolic stability. The compound exhibits excellent bench stability and facilitates straightforward purification, making it well-suited for both small-molecule library synthesis and modular drug discovery workflows.
