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-Chloro-3-methylpyrazine-2-carbonitrile features a pyrazine core functionalized with chlorine, methyl, and nitrile groups, enabling direct integration into heterocyclic scaffolds. The electron-deficient ring facilitates nucleophilic substitution, while the nitrile group serves as a handle for downstream derivatization. This compound demonstrates stability under standard bench conditions and is compatible with common synthetic protocols in medicinal chemistry and materials science.

Application

5-Chloro-3-methylpyrazine-2-carbonitrile serves as a versatile building block in heterocyclic synthesis, enabling efficient access to substituted pyrazine scaffolds. Its complementary electron-withdrawing nitrile and chloro groups facilitate palladium-catalyzed cross-coupling reactions, while the methyl substituent provides a handle for further functionalization. The compound exhibits good bench stability and is compatible with standard synthetic workflows, making it a practical choice for medicinal chemistry and process development applications.
