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

4-Chloro-2-methoxy-5-nitropyridine features a trifunctional pyridine core with complementary reactivity: the chlorine enables palladium-catalyzed cross-coupling, the methoxy group offers steric and electronic modulation, and the nitro substituent serves as a strong electron-withdrawing anchor for further functionalization. This scaffold integrates readily into complex heterocyclic architectures under standard conditions.

Application

4-Chloro-2-methoxy-5-nitropyridine serves as a versatile building block in medicinal chemistry, enabling palladium-catalyzed cross-coupling reactions due to its reactive chloropyridine moiety. The methoxy and nitro groups provide orthogonal functional handles for selective derivatization, while the compound exhibits good bench stability and facilitates efficient purification. Its defined substitution pattern supports predictable reactivity in heterocyclic scaffold construction.
