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

6-Bromo-[1,2,3]triazolo[1,5-a]pyridine is a heterocyclic scaffold featuring a brominated triazolopyridine core, offering a reactive handle for transition-metal-catalyzed coupling reactions. This electron-deficient system integrates readily into complex molecular architectures, enabling efficient access to functionalized nitrogen-rich frameworks in medicinal chemistry and materials science applications.

Application

6-Bromo-[1,2,3]triazolo[1,5-a]pyridine serves as a versatile heterocyclic building block for transition-metal-catalyzed cross-coupling reactions. Its bromine substituent enables reliable Suzuki, Stille, and Negishi couplings, facilitating the construction of biaryl and extended π-conjugated systems. The triazolopyridine core exhibits excellent bench stability, tolerates diverse functional groups, and simplifies purification due to its crystalline nature—making it well-suited for medicinal chemistry and materials synthesis workflows.
