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-Amino-5,6-dichloropyridine features a pyridine core functionalized with amino and dichloro substituents at strategic positions, enabling selective coupling reactions. The electron-deficient ring system enhances reactivity in nucleophilic substitution processes, while the amino group provides a handle for further derivatization. This compound serves as a key intermediate in medicinal chemistry and agrochemical synthesis, offering high stability under standard bench conditions.

Application

3-Amino-5,6-dichloropyridine serves as a versatile building block in medicinal chemistry, enabling efficient access to substituted pyridine scaffolds via Suzuki-Miyaura and Buchwald-Hartwig coupling reactions. Its ortho-dichloro substitution pattern facilitates selective functionalization, while the amino group offers direct derivatization potential. The compound exhibits excellent bench stability and is readily purified by recrystallization, making it well-suited for scalable synthesis of API intermediates and heterocyclic libraries.
