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

4-Bromo-2,5-dimethylindazole is a sterically hindered heterocycle featuring bromine and methyl substituents at strategic positions, enabling direct functionalization in cross-coupling reactions. This electron-deficient indazole scaffold integrates readily into bioactive molecules and serves as a robust building block for medicinal chemistry campaigns requiring metabolic stability and defined polarity.

Application

4-Bromo-2,5-dimethylindazole serves as a versatile building block in medicinal chemistry, enabling palladium-catalyzed cross-coupling reactions due to its stable bromo functionality and electron-rich heterocyclic core. The methyl groups enhance solubility and provide steric modulation, while the indazole scaffold offers metabolic stability and favorable binding interactions. Its bench-stable nature and compatibility with standard reaction conditions facilitate efficient synthesis of complex pharmaceutical intermediates.
