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-5-methyl-1H-1,2,4-triazole features a brominated triazole core with a methyl group at the 5-position, offering enhanced reactivity in cross-coupling and functionalization workflows. The electron-deficient triazole ring facilitates nucleophilic substitution, while the methyl substituent improves solubility and stability under standard conditions. This compound serves as a key intermediate in medicinal chemistry and agrochemical synthesis.

Application

3-Bromo-5-methyl-1H-1,2,4-triazole serves as a versatile building block in medicinal chemistry and heterocyclic synthesis. The bromo group enables palladium-catalyzed cross-coupling reactions, while the methyl substituent enhances solubility and modulates electronic properties. Its stability under standard bench conditions facilitates straightforward handling and purification. Functions effectively in Suzuki-Miyaura, Sonogashira, and Buchwald-Hartwig transformations to construct complex triazolyl scaffolds relevant to pharmaceutical development.
