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

6-Bromo-8-fluoroisoquinolin-1(2H)-one features a fused heterocyclic core with strategically positioned halogen substituents, enabling direct functionalization in cross-coupling and C–H activation reactions. The electron-deficient quinolinone scaffold enhances reactivity in transition metal catalysis, while the bromo and fluoro groups offer orthogonal handles for sequential derivatization. This compound serves as a key building block in medicinal chemistry and materials science.

Application

6-Bromo-8-fluoroisoquinolin-1(2H)-one serves as a versatile building block for the synthesis of bioactive heterocycles, enabling palladium-catalyzed cross-coupling reactions due to its well-defined halogen reactivity. The bromo and fluoro substituents offer orthogonal functionalization potential, while the isoquinolinone core provides structural rigidity and hydrogen-bonding capacity. This compound exhibits excellent bench stability and facilitates efficient purification, making it ideal for medicinal chemistry campaigns and process development in API synthesis.
