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-3,7-dimethyl-1H-indazole delivers a sterically hindered, electron-deficient heterocyclic scaffold ideal for transition-metal-catalyzed coupling reactions. The bromine at the 5-position enables direct functionalization, while the methyl groups at C3 and C7 enhance solubility and stability under standard conditions. This compound serves as a key building block in medicinal chemistry and materials science.

Application

5-Bromo-3,7-dimethyl-1H-indazole serves as a versatile building block in medicinal chemistry, enabling direct functionalization at the bromine site via palladium-catalyzed cross-coupling reactions. The methyl groups at C3 and C7 enhance metabolic stability and modulate electronic properties, while the indazole core provides a rigid, hydrogen-bonding scaffold suitable for target engagement. Bench-stable and readily purified by chromatography, it facilitates efficient access to diverse heterocyclic architectures in API development workflows.
