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

1-Boc-3-Ethynylpiperidine features a protected piperidine core with a terminal alkyne handle, enabling direct incorporation into click chemistry workflows. The Boc group ensures stability and ease of deprotection, while the ethynyl moiety facilitates efficient CuAAC or strain-promoted cycloadditions. This compound serves as a modular building block for bioconjugation and medicinal chemistry applications.

Application

1-Boc-3-Ethynylpiperidine serves as a versatile building block in medicinal chemistry, enabling efficient access to functionalized piperidine scaffolds via mild deprotection and subsequent coupling reactions. The Boc group provides excellent stability under basic conditions and facilitates straightforward purification, while the terminal alkyne supports robust copper-catalyzed azide-alkyne cycloaddition (CuAAC) for rapid heterocycle construction. Its compatibility with diverse reaction conditions makes it well-suited for parallel synthesis and API intermediate development.
