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

This cyclopentadienone scaffold features four phenyl substituents that enhance π-conjugation and steric protection, stabilizing the reactive enone system. The ortho-quinoid resonance structure imparts electron-deficient character, enabling use in Diels-Alder reactions and transition-metal-catalyzed coupling processes under standard bench conditions.

Application

2,3,4,5-Tetraphenylcyclopenta-2,4-dien-1-one serves as a versatile building block in organic synthesis, enabling access to complex polycyclic architectures through Diels-Alder reactions and subsequent functionalization. Its rigid, planar structure and conjugated enone system offer predictable reactivity, facilitating efficient transformations under mild conditions. The molecule exhibits good bench stability and is compatible with a range of functional groups, making it valuable for the construction of fused heterocycles and advanced intermediates in medicinal chemistry workflows.
