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

8-Bromo-6-methyl-[1,2,4]triazolo[4,3-a]pyridin-3(2H)-one is a heterocyclic scaffold featuring a brominated triazolopyridinone core with methyl substitution at the 6-position. This electron-deficient system enables direct functionalization in transition metal-catalyzed coupling reactions and serves as a key building block for bioactive molecules in medicinal chemistry.

Application

8-Bromo-6-methyl-[1,2,4]triazolo[4,3-a]pyridin-3(2H)-one serves as a versatile heterocyclic building block for medicinal chemistry and catalytic synthesis. The molecule combines a bromo substituent at C8 with a methyl group at C6, enabling late-stage functionalization via palladium-catalyzed cross-coupling. Its triazolopyridinone core exhibits favorable bench stability, moderate solubility, and compatibility with common reaction conditions, facilitating efficient incorporation into complex scaffolds.
