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

5-Bromo-1H-indazole is a heterocyclic compound featuring a bromine substituent at the 5-position of the indazole scaffold. This electron-deficient aryl halide enables direct functionalization in cross-coupling reactions, facilitating the synthesis of complex biaryl architectures. The molecule exhibits enhanced stability under standard bench conditions and demonstrates favorable solubility in common organic solvents, making it a reliable building block for medicinal chemistry and materials science applications.

Application

5-Bromo-1H-indazole serves as a versatile building block in medicinal chemistry, enabling palladium-catalyzed cross-coupling reactions for the construction of biologically relevant heterocyclic scaffolds. The bromine substituent facilitates reliable C–C bond formation under standard Suzuki, Stille, or Negishi conditions, while the indazole core provides a stable, planar platform with moderate hydrogen-bonding capacity. Its bench-stable crystalline form supports straightforward handling and purification, making it well-suited for iterative synthesis campaigns in drug discovery.
