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-[1,2,3]triazolo[1,5-a]pyridine is a heterocyclic building block featuring a brominated triazolopyridine core. This electron-deficient scaffold enables efficient coupling in cross-coupling reactions and serves as a key intermediate in the synthesis of bioactive compounds. The bromine substituent facilitates further functionalization under palladium-catalyzed conditions.

Application

5-Bromo-[1,2,3]triazolo[1,5-a]pyridine serves as a versatile heterocyclic building block for medicinal chemistry and catalytic cross-coupling applications. The bromine substituent enables reliable Suzuki-Miyaura and Buchwald-Hartwig reactions, facilitating the construction of biaryl and amino-substituted scaffolds. Its inherent stability under standard reaction conditions and compatibility with diverse functional groups make it a practical choice for iterative synthesis and library generation.
