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+

Description

N-(Prop-2-yn-1-yl)acetamide features a terminal alkyne group flanked by a polar amide functionality, enabling efficient copper-catalyzed azide-alkyne cycloaddition. This bifunctional scaffold integrates readily into bioconjugation workflows and small-molecule libraries, offering high chemoselectivity and compatibility under standard bench conditions.

Application

N-(Prop-2-yn-1-yl)acetamide serves as a versatile synthetic building block, enabling efficient access to functionalized alkynes via straightforward derivatization. The propargylic amide functionality exhibits excellent bench stability and compatibility with standard coupling protocols. It functions effectively in copper-catalyzed azide-alkyne cycloaddition (CuAAC), facilitating rapid construction of triazole-linked scaffolds commonly employed in medicinal chemistry and materials science. Its moderate reactivity profile allows for selective transformations under mild conditions, supporting purification by standard chromatographic techniques.
