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

3-Bromo-1-methyl-1H-1,2,4-triazole is a bench-stable triazole derivative featuring a bromine substituent at the 3-position and a methyl group at nitrogen-1. This combination imparts enhanced electrophilicity and facilitates downstream functionalization in cross-coupling reactions. The molecule integrates readily into bioactive scaffolds due to its polar heterocyclic core and halogen handle, enabling efficient diversification in medicinal chemistry campaigns.

Application

3-Bromo-1-methyl-1H-1,2,4-triazole serves as a versatile building block in medicinal chemistry and heterocyclic synthesis. The bromine substituent enables palladium-catalyzed cross-coupling reactions, while the 1-methyl-1H-1,2,4-triazole core provides metabolic stability and hydrogen-bonding capability. It exhibits excellent bench stability, facilitates straightforward purification, and demonstrates broad functional group tolerance, making it well-suited for constructing bioactive scaffolds and API intermediates.
