    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

5,6-Dimethyl-3-oxo-3,4-dihydropyrazine-2-carboxylic acid features a fused heterocyclic core with dual methyl substituents and a carboxylic acid functionality, enabling integration into bioactive molecule scaffolds. The electron-deficient pyrazine ring facilitates nucleophilic addition and transition-metal-catalyzed coupling reactions. This bench-stable, moisture-tolerant reagent supports efficient access to functionalized dihydropyrazine derivatives in synthetic and medicinal chemistry workflows.

Application

5,6-Dimethyl-3-oxo-3,4-dihydropyrazine-2-carboxylic acid serves as a versatile heterocyclic building block for medicinal chemistry and synthetic organic applications. Its conjugated diketone-carboxylic acid motif enables facile functionalization via nucleophilic addition, condensation, and metal-catalyzed coupling reactions. The molecule exhibits good bench stability and facilitates access to substituted pyrazine scaffolds relevant in bioactive compound synthesis.
