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-[1,2,4]triazolo[4,3-a]pyridin-3(2H)-one is a bench-stable heterocyclic scaffold featuring a bromine substituent at the 6-position and a lactam functionality at C3. This electron-deficient triazolopyridinone core enables direct coupling in transition-metal-catalyzed transformations, facilitating rapid access to diverse bioactive compounds in medicinal chemistry and chemical biology applications.

Application

6-Bromo-[1,2,4]triazolo[4,3-a]pyridin-3(2H)-one serves as a versatile heterocyclic building block for medicinal chemistry and catalytic cross-coupling applications. The bromine substituent enables palladium-catalyzed coupling reactions with broad functional group tolerance, while the triazolopyridinone core provides structural rigidity and hydrogen-bonding capacity. Bench-stable and readily purified, it facilitates efficient synthesis of complex scaffolds relevant to kinase inhibitors and other bioactive molecules.
