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

3-Bromo-1H-pyrazol-5-amine features a bromine substituent at the 3-position and an amine group at the 5-position of the pyrazole ring, enabling direct functionalization in heterocyclic synthesis. This electron-deficient scaffold integrates readily into bioactive molecule design, offering high reactivity in palladium-catalyzed coupling reactions. The compound exhibits bench-stable handling under standard conditions and serves as a key intermediate in medicinal chemistry and materials science applications.

Application

3-Bromo-1H-pyrazol-5-amine serves as a versatile building block for heterocyclic synthesis, enabling palladium-catalyzed cross-coupling reactions to construct biologically relevant pyrazole derivatives. The bromo group facilitates efficient Suzuki, Stille, and Negishi couplings, while the primary amine offers direct functionalization potential. Its bench-stable crystalline form simplifies handling and purification, making it well-suited for medicinal chemistry campaigns and API intermediate development.
