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-chloro-6-ethylpyrazine-2-carbonitrile features a pyrazine core functionalized with bromo, chloro, ethyl, and nitrile groups, enabling diverse coupling reactions. The electron-deficient ring facilitates transition metal-catalyzed transformations, while the nitrile moiety offers synthetic versatility for downstream derivatization. This compound serves as a key building block in pharmaceutical and agrochemical synthesis.

Application

3-Bromo-5-chloro-6-ethylpyrazine-2-carbonitrile serves as a versatile heterocyclic building block for medicinal chemistry and agrochemical synthesis. Its complementary halogenation pattern enables sequential cross-coupling reactions, while the nitrile group offers a handle for functionalization via hydrolysis or nucleophilic addition. The ethyl substituent enhances solubility and modulates electronic properties, supporting efficient derivatization in standard transition-metal-catalyzed transformations.
