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

4-Bromoquinolin-2-one features a bromine substituent at the C4 position of a quinolin-2-one scaffold, introducing a reactive handle for cross-coupling transformations. The electron-deficient quinoline core enhances its utility in transition-metal-catalyzed reactions, while the ketone functionality provides a site for nucleophilic addition or derivatization. This compound serves as a versatile intermediate in medicinal chemistry and materials synthesis.

Application

4-Bromoquinolin-2-one serves as a versatile building block in medicinal chemistry and synthetic organic chemistry, enabling direct functionalization at the C4 position via palladium-catalyzed cross-coupling reactions. Its stability under standard reaction conditions, combined with excellent functional group tolerance, facilitates efficient access to diverse quinolinone-based scaffolds relevant to pharmaceutical development. The molecule functions as a key intermediate for constructing bioactive heterocycles and supports scalable synthesis workflows.
