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

5-Methylpyrazin-2(1H)-one is a bench-stable, electron-deficient heterocycle featuring a methyl-substituted pyrazinone core. This compound integrates readily into synthetic sequences requiring nitrogen-rich scaffolds and serves as a key building block in medicinal chemistry for bioactive molecule development.

Application

5-Methylpyrazin-2(1H)-one serves as a versatile heterocyclic building block in medicinal chemistry, enabling efficient access to pyrazine-based scaffolds through standard functionalization protocols. Its stability under ambient conditions and compatibility with diverse reaction conditions facilitate straightforward derivatization, including nucleophilic substitution and transition-metal-catalyzed coupling. The compound functions effectively as a key intermediate in the synthesis of bioactive molecules, particularly those requiring nitrogen-rich frameworks with defined electronic properties.
