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

6-Bromo-4H-chromen-4-one features a brominated coumarin core with a reactive ketone at the C4 position, enabling direct functionalization in cross-coupling and nucleophilic substitution reactions. The electron-deficient aromatic system enhances reactivity in transition metal-catalyzed processes, while the bench-stable crystalline form facilitates handling under standard conditions.

Application

6-Bromo-4H-chromen-4-one serves as a versatile building block in synthetic organic chemistry, enabling direct functionalization at the C6 position and facilitating Suzuki-Miyaura and Stille coupling reactions. Its stability under standard reaction conditions and compatibility with diverse functional groups make it ideal for constructing substituted coumarin scaffolds used in medicinal chemistry and materials science.
