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+

Description

4-(Prop-2-yn-1-yl)morpholine is a versatile synthetic intermediate featuring a reactive terminal alkyne group appended to a morpholine ring. This structure enables efficient copper-catalyzed azide-alkyne cycloaddition (CuAAC) for bioconjugation and click chemistry applications. The molecule exhibits excellent solubility in common organic solvents and maintains stability under standard bench conditions, facilitating straightforward handling in process development workflows.

Application

4-(Prop-2-yn-1-yl)morpholine serves as a versatile building block in medicinal chemistry, enabling efficient access to diverse heterocyclic scaffolds via copper-catalyzed azide-alkyne cycloaddition (CuAAC). The terminal alkyne functionality offers high reactivity and compatibility with standard click chemistry protocols, while the morpholine ring provides favorable solubility and metabolic stability. Bench-stable and readily purified by silica gel chromatography, it functions reliably in multi-step syntheses requiring orthogonal functional group handling.
