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

7-Bromo-3,4-dihydro-1H-quinolin-2-one features a brominated quinolinone core with enhanced electrophilicity at the C2 position. This bench-stable scaffold integrates readily into synthetic sequences requiring halogenation or transition-metal-catalyzed coupling. The electron-deficient ring system supports efficient functionalization in medicinal chemistry and materials development.

Application

7-Bromo-3,4-dihydro-1H-quinolin-2-one serves as a versatile building block in medicinal chemistry, enabling direct functionalization at C2 via nucleophilic substitution or transition-metal-catalyzed coupling. Its bromine substituent facilitates cross-coupling reactions with broad functional group tolerance, while the lactam carbonyl supports hydrogen bonding and conformational rigidity. The compound exhibits excellent bench stability and is readily purified by flash chromatography, making it ideal for scalable synthesis of quinoline-based scaffolds in drug discovery programs.
