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.

Type	HazMat Fee
Excepted Quantity	$0.00

Description

Ethyl 5-methyl-1,2,4-oxadiazole-3-carboxylate features a stable oxadiazole core with a methyl-substituted position and an ethyl ester handle. This bench-stable heterocycle integrates readily into synthetic sequences requiring electron-deficient scaffolds. The functional group combination enables efficient coupling reactions and serves as a key intermediate in the development of bioactive molecules and advanced materials.

Application

Ethyl 5-methyl-1,2,4-oxadiazole-3-carboxylate serves as a versatile building block in medicinal chemistry, enabling efficient access to bioactive heterocycles. The oxadiazole core exhibits excellent metabolic stability and functions as a robust hydrogen-bond acceptor. It readily participates in cross-coupling reactions and acts as a surrogate for carboxylic acids or esters in scaffold diversification. Its bench-stable nature and straightforward purification facilitate integration into multi-step syntheses.
