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

7-Chloropyrido[3,4-b]pyrazine is a heteroaromatic scaffold featuring a chlorinated pyridopyrazine core. This electron-deficient system integrates readily into medicinal chemistry campaigns, offering a rigid, planar framework for kinase inhibitor design. The chlorine substituent enhances binding affinity through dipole interactions and contributes to metabolic stability in biological assays.

Application

7-Chloropyrido[3,4-b]pyrazine serves as a versatile heterocyclic building block for medicinal chemistry and materials science. Its electron-deficient pyridopyrazine core enables efficient transition metal-catalyzed coupling reactions, particularly in Suzuki-Miyaura and Buchwald-Hartwig protocols. The chlorine substituent provides a reliable handle for nucleophilic displacement, facilitating the installation of diverse aryl, heteroaryl, and amine functionalities under mild conditions. Bench-stable and readily purified by flash chromatography, it functions effectively in multi-step synthesis of kinase inhibitors and other bioactive scaffolds.
