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

2,3-Dichloro-5,6-dimethylpyrazine features a rigid pyrazine core with chlorine substituents at the 2,3-positions and methyl groups at the 5,6-positions, imparting enhanced electron deficiency and steric shielding. This configuration enables stable coupling in transition-metal-catalyzed transformations and facilitates incorporation into functionalized heterocyclic architectures for materials science and medicinal chemistry applications.

Application

2,3-Dichloro-5,6-dimethylpyrazine serves as a versatile heterocyclic building block in medicinal chemistry and agrochemical synthesis. Its electron-deficient pyrazine core enables selective nucleophilic substitution reactions, while the methyl groups provide steric and electronic modulation. The molecule exhibits good bench stability and facilitates efficient functionalization under mild conditions, making it valuable for constructing complex nitrogen-containing scaffolds in API development.
