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-Bromo-5-methoxypyridin-2(1H)-one features a bromine substituent at the 4-position and a methoxy group at the 5-position on a pyridinone scaffold. This electron-deficient heterocycle integrates readily into cross-coupling reactions, offering high functional group tolerance and stability under standard conditions.

Application

4-Bromo-5-methoxypyridin-2(1H)-one serves as a versatile building block in medicinal chemistry, enabling palladium-catalyzed cross-coupling reactions due to its stable bromo substituent. The pyridinone core provides hydrogen-bonding capacity and enhanced solubility, while the methoxy group offers moderate electronic modulation. Its bench-stable crystalline form facilitates handling and purification, making it well-suited for iterative synthesis of heterocyclic scaffolds and API intermediates.
