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

4-Bromo-1-methyl-1H-1,2,3-triazole features a bromine substituent at the C4 position and a methyl group at nitrogen-1, delivering a highly functionalized triazole scaffold. This bench-stable heterocycle integrates readily into click chemistry workflows, enabling efficient coupling with azides under mild conditions. The electron-deficient triazole ring enhances reactivity in transition-metal-catalyzed transformations, facilitating the synthesis of complex bioconjugates and pharmaceutical intermediates.

Application

4-Bromo-1-methyl-1H-1,2,3-triazole serves as a versatile building block in medicinal chemistry and cross-coupling synthesis. The bromine atom enables palladium-catalyzed transformations such as Suzuki, Stille, and Sonogashira reactions, while the methyl-substituted triazole core provides stability and orthogonal reactivity. Its bench-stable nature and compatibility with diverse functional groups make it ideal for modular scaffold construction in API development and combinatorial library synthesis.
