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.

Type	HazMat Fee

Description

4-Bromo-7-chloro-1H-indazole is a halogenated indazole scaffold featuring complementary reactive sites for cross-coupling and functionalization. The electron-deficient core enables efficient palladium-catalyzed transformations, while the bromine and chlorine substituents offer orthogonal reactivity. This compound serves as a key building block in medicinal chemistry and materials science.

Application

4-Bromo-7-chloro-1H-indazole serves as a versatile building block for the synthesis of biologically active heterocycles, enabling palladium-catalyzed cross-coupling reactions at both halogen sites. Its complementary reactivity profile facilitates sequential functionalization in medicinal chemistry and materials science. The molecule exhibits excellent bench stability, simplifies purification, and functions effectively in standard coupling protocols such as Suzuki-Miyaura and Stille reactions.
