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

5-Bromo-3,4-dihydro-2(1H)-quinolinone features a brominated quinolinone core with enhanced electrophilicity at the C5 position. This scaffold integrates readily into transition-metal-catalyzed couplings and serves as a key intermediate in medicinal chemistry. The compound exhibits excellent stability under standard conditions and facilitates efficient derivatization for drug discovery applications.

Application

5-Bromo-3,4-dihydro-2(1H)-quinolinone serves as a versatile building block in medicinal chemistry, enabling late-stage functionalization via palladium-catalyzed cross-coupling reactions. The bromine substituent provides high reactivity in Suzuki, Stille, and Negishi couplings, while the saturated quinolinone core offers favorable solubility and stability under standard reaction conditions. Its well-defined regiochemistry facilitates predictable transformations, making it ideal for constructing complex heterocyclic scaffolds in API development.
