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'-Benzyloxyphenyl acetylene features a para-benzyloxy-substituted phenyl ring linked to an acetylene handle, enabling efficient copper-catalyzed coupling reactions. The benzyl ether group enhances solubility and stability under standard conditions, while the terminal alkyne facilitates conjugation in functional materials and bioconjugation workflows.

Application

4'-Benzyloxyphenyl acetylene serves as a versatile building block for copper-catalyzed azide-alkyne cycloaddition (CuAAC) reactions, enabling efficient access to triazole-linked molecular architectures. The benzyloxy group provides orthogonal protection and enhances solubility, while the terminal alkyne exhibits high reactivity under standard click chemistry conditions. This compound demonstrates excellent bench stability and facilitates straightforward purification, making it well-suited for iterative synthesis in medicinal chemistry and materials science applications.
