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-Chloro-2-methyl-2H-indazole is a heterocyclic scaffold featuring a chlorine substituent at the 6-position and a methyl group at the 2-position, offering enhanced electron-deficient character and improved solubility in polar organic solvents. This configuration supports efficient coupling reactions and facilitates incorporation into bioactive molecules for medicinal chemistry applications.

Application

6-Chloro-2-methyl-2H-indazole serves as a versatile heterocyclic building block in medicinal chemistry, enabling efficient access to bioactive scaffolds through palladium-catalyzed cross-coupling reactions. The chlorine atom at the 6-position provides a reliable handle for C–C bond formation, while the methyl group at the 2-position enhances metabolic stability and modulates electronic properties. Its bench-stable nature and compatibility with diverse reaction conditions make it well-suited for iterative synthesis workflows in API development.
