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.

Description

Ethyl pent-4-ynoate is a linear alkyne-containing ester featuring a terminal triple bond flanked by a carbonyl group. This configuration enables direct participation in copper-catalyzed coupling reactions, including Sonogashira and Glaser-type processes. The molecule exhibits high stability under standard conditions and integrates readily into complex molecular architectures requiring precise alkyne handles.

Application

Ethyl pent-4-ynoate serves as a versatile building block in synthetic organic chemistry, enabling efficient access to conjugated enynes and heterocyclic systems via [2+2] cycloadditions and transition-metal-catalyzed couplings. Its terminal alkyne functionality exhibits excellent stability under standard bench conditions and tolerates a range of functional groups, facilitating straightforward purification and integration into multi-step syntheses.
