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.

Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

8-Bromo-2-methylisoquinolin-1(2H)-one features a brominated isoquinolinone core with a methyl group at the 2-position, offering enhanced electron-withdrawing character and improved metabolic stability. This scaffold serves as a key building block in medicinal chemistry for kinase inhibitors and targeted therapeutics.

Application

8-Bromo-2-methylisoquinolin-1(2H)-one serves as a versatile building block in medicinal chemistry, enabling direct functionalization at the C8 position via palladium-catalyzed cross-coupling. The isoquinolinone core provides a rigid, planar scaffold with enhanced metabolic stability, while the bromo and methyl groups offer orthogonal handles for further derivatization. Bench-stable and compatible with standard coupling conditions, it facilitates rapid access to complex heterocyclic architectures relevant to kinase inhibitor and CNS-targeted compound discovery.
