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-1,2,4-oxadiazole features a bromine substituent at C3 and a methyl group at C5 on the 1,2,4-oxadiazole ring, delivering enhanced reactivity for cross-coupling transformations. The electron-deficient heterocycle enables efficient palladium-catalyzed coupling reactions under mild conditions, while the bench-stable structure supports reliable handling in synthetic workflows.

Application

3-Bromo-5-methyl-1,2,4-oxadiazole serves as a versatile heterocyclic building block in medicinal chemistry and synthetic organic chemistry. Its bromine substituent enables palladium-catalyzed cross-coupling reactions, while the oxadiazole core provides metabolic stability and favorable polarity. The methyl group enhances lipophilicity and offers a handle for further functionalization. This compound exhibits good bench stability and is compatible with standard purification methods, facilitating integration into multi-step synthesis workflows.
