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

2H-Indazole is a nitrogen-rich heterocycle featuring fused pyrazole and benzene rings, offering high stability and favorable electronic properties. This scaffold integrates readily into bioactive molecules due to its planar geometry and ability to form hydrogen bonds. It serves as a key pharmacophore in medicinal chemistry, particularly for kinase inhibitors and CNS-targeted therapeutics.

Application

2H-Indazole serves as a versatile heterocyclic building block in medicinal chemistry, enabling efficient synthesis of bioactive compounds through direct functionalization at the 1- and 3-positions. Its stability under standard reaction conditions and compatibility with common coupling protocols facilitate rapid access to diverse scaffolds, including kinase inhibitors and CNS-targeted agents. The core structure functions as a privileged pharmacophore in drug discovery pipelines.
