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

Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

Cyclooct-4-enol is a strained, electron-rich cyclic enol featuring a conjugated diene system within an eight-membered ring. This labile structure exhibits enhanced reactivity in electrophilic addition and cycloaddition processes due to ring strain and oxygen lone-pair delocalization. The hydroxyl group enables direct functionalization or derivatization under mild conditions, facilitating access to complex carbocyclic architectures.

Application

Cyclooct-4-enol serves as a versatile synthetic intermediate for strained ring systems and functionalized cycloalkenes. Its conjugated enol functionality enables direct participation in electrophilic additions, Diels–Alder reactions, and metal-catalyzed transformations. The molecule exhibits sufficient bench stability for routine handling and facilitates clean functionalization at the hydroxyl and alkene sites, making it valuable for constructing complex heterocyclic scaffolds and natural product analogs.
