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+

Description

4-(Prop-2-yn-1-yl)piperidine hydrochloride features a terminal alkyne group tethered to a piperidine nitrogen, enabling efficient copper-catalyzed azide-alkyne cycloaddition (CuAAC) for bioconjugation and click chemistry applications. The hydrochloride salt enhances solubility and stability in aqueous and polar organic media, facilitating handling under standard bench conditions.

Application

4-(Prop-2-yn-1-yl)piperidine hydrochloride serves as a versatile building block in medicinal chemistry, enabling efficient access to alkynyl-functionalized heterocycles via copper-catalyzed azide-alkyne cycloaddition (CuAAC). The terminal alkyne group exhibits high reactivity in click chemistry protocols, while the piperidine nitrogen provides a handle for further derivatization. Its crystalline hydrochloride salt ensures excellent bench stability, ease of handling, and straightforward purification—ideal for scalable synthesis and library generation.
