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

This 2-(4-bromophenyl)-1H-1,2,4-triazol-3(2H)-one features a brominated phenyl group appended to a triazolone scaffold, delivering enhanced electronic and steric character. The system integrates readily into medicinal chemistry campaigns targeting kinase inhibition and antimicrobial agents. Bench-stable and moisture-tolerant, it serves as a robust building block for diverse heterocyclic synthesis under standard conditions.

Application

2-(4-Bromophenyl)-1H-1,2,4-triazol-3(2H)-one serves as a versatile building block for the synthesis of triazolyl-substituted biaryl scaffolds. Its bromine functionality enables palladium-catalyzed cross-coupling reactions, including Suzuki and Stille couplings, facilitating access to complex heterocyclic systems. The triazolone core exhibits good bench stability and tolerates a range of functional groups, enabling efficient incorporation into medicinal chemistry campaigns and materials science applications.
