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 carbonyl-bridged coumarin dimer features two electron-rich diethylamino-substituted chromenone units linked by a central carbonyl group, enabling efficient intramolecular energy transfer. The extended π-conjugation delivers strong fluorescence with high quantum yield, while the sterically shielded structure enhances photostability under prolonged irradiation. Designed for use in organic light-emitting materials and fluorescent sensors, this compound offers excellent solubility in common aprotic solvents and maintains stability under standard bench conditions.

Application

3,3'-Carbonylbis(7-(diethylamino)-2H-chromen-2-one) serves as a versatile bis-fluorescent chromophore scaffold, enabling efficient construction of extended π-conjugated systems. Its rigid, planar structure and electron-rich diethylamino groups facilitate strong intramolecular charge transfer, making it valuable for dye synthesis and materials applications. The compound exhibits good bench stability and facilitates straightforward purification, supporting scalable use in organic synthesis and functional material development.
