    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-Iodopyrazine is a bench-stable, electron-deficient heterocycle featuring a reactive iodine substituent at the 2-position. This configuration enables direct functionalization via cross-coupling reactions, making it a valuable scaffold for constructing complex pyrazine-based architectures in medicinal chemistry and materials science.

Application

2-Iodopyrazine serves as a versatile building block in cross-coupling chemistry, enabling efficient access to functionalized pyrazine scaffolds. Its iodine substituent facilitates palladium-catalyzed coupling reactions with arylboranes, alkynes, and other nucleophiles under mild conditions. The compound exhibits excellent bench stability, ease of handling, and compatibility with diverse functional groups, making it ideal for constructing complex heterocyclic architectures in medicinal chemistry and materials science applications.
