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.

Type	HazMat Fee
Excepted Quantity	$0.00

Description

3-Bromo-5-fluoropyridin-2(1H)-one features a fused heterocyclic core bearing strategically positioned halogen substituents, enabling direct functionalization in cross-coupling and nucleophilic substitution reactions. The electron-deficient pyridinone scaffold enhances reactivity toward amines and thiols, while the bromine and fluorine atoms provide orthogonal handles for sequential derivatization. This bench-stable compound integrates readily into complex molecular architectures used in medicinal chemistry and materials science.

Application

3-Bromo-5-fluoropyridin-2(1H)-one serves as a versatile building block in medicinal chemistry, enabling palladium-catalyzed cross-coupling reactions due to its orthogonal reactivity profile. The bromo group facilitates C–C bond formation under standard Suzuki, Stille, or Negishi conditions, while the fluorine and lactam functionalities provide enhanced metabolic stability and hydrogen-bonding capacity. Its bench-stable crystalline nature simplifies handling and purification, making it ideal for modular synthesis of bioactive heterocycles and API intermediates.
