    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

2,7-Di-tert-butylpyrene-4,5,9,10-tetraone features a sterically shielded pyrene core with four electron-deficient ketone groups, enabling robust stability and enhanced solubility in organic solvents. This architecture facilitates use in high-performance materials, where controlled reactivity and resistance to degradation are critical.

Application

2,7-Di-tert-butylpyrene-4,5,9,10-tetraone serves as a sterically hindered polycyclic aromatic scaffold with high thermal stability and enhanced solubility due to bulky tert-butyl groups. Its four ketone functionalities enable versatile functionalization in multi-step syntheses, particularly for constructing complex heterocyclic systems and molecular frameworks relevant to organic semiconductors and advanced materials. The molecule exhibits excellent bench stability and facilitates straightforward purification, making it well-suited for iterative synthetic workflows in industrial R&D settings.
