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-pyrazolo[3,4-b]pyrazine is a heterocyclic scaffold featuring a brominated pyrazolo[3,4-b]pyrazine core, offering a rigid, electron-deficient platform for synthetic modification. This moiety integrates readily into pharmaceutical intermediates and functional materials due to its stability and compatibility with cross-coupling reactions.

Application

5-Bromo-1H-pyrazolo[3,4-b]pyrazine serves as a versatile heterocyclic building block for medicinal chemistry and materials science applications. The bromine substituent enables palladium-catalyzed cross-coupling reactions, facilitating the construction of biaryl and functionalized pyrazolo[3,4-b]pyrazine scaffolds. Its stability under standard reaction conditions and compatibility with diverse functional groups make it well-suited for iterative synthesis workflows in drug discovery and advanced material development.
