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-1-methyl-1H-indazol-3(2H)-one features a brominated indazolone core with a methyl group at the nitrogen, offering a reactive site for cross-coupling and a stable scaffold for medicinal chemistry. This bench-stable heterocycle integrates readily into bioactive molecules, enabling efficient access to functionalized analogs in drug discovery workflows.

Application

6-Bromo-1-methyl-1H-indazol-3(2H)-one serves as a versatile building block in medicinal chemistry, enabling direct functionalization at the C6 position via palladium-catalyzed cross-coupling reactions. The bromo group exhibits high reactivity in Suzuki, Stille, and Negishi couplings, while the 3(2H)-one carbonyl supports enolization and metal coordination. Its bench-stable crystalline form facilitates handling and purification, making it well-suited for iterative synthesis of indazole-based pharmaceutical scaffolds.
