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

7-Bromo-3-chloro-1H-indazole is a halogenated indazole scaffold featuring complementary reactivity at the 7-bromo and 3-chloro positions. This electron-deficient heterocycle integrates readily into cross-coupling processes, enabling efficient access to functionalized derivatives in medicinal chemistry and materials science. The molecule exhibits enhanced stability under standard conditions and facilitates precise molecular diversification through orthogonal transformation pathways.

Application

7-Bromo-3-chloro-1H-indazole serves as a versatile building block in medicinal chemistry, enabling direct functionalization at both the 3- and 7-positions. Its dual halogenation pattern facilitates palladium-catalyzed cross-coupling reactions with broad functional group tolerance. The compound exhibits excellent bench stability and ease of purification, making it well-suited for modular synthesis of bioactive heterocycles and API candidates.
