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-Chloro-5-nitropyridine is a heterocyclic building block featuring a chlorine atom at the 2-position and a nitro group at the 5-position on the pyridine ring. This electron-deficient scaffold enables direct functionalization in cross-coupling reactions, facilitating the synthesis of complex pharmaceutical intermediates and agrochemicals under mild conditions.

Application

2-Chloro-5-nitropyridine serves as a versatile building block in synthetic organic chemistry, enabling direct functionalization at the C2 position via palladium-catalyzed cross-coupling reactions. Its electron-deficient pyridine core enhances reactivity in nucleophilic substitution processes, while the nitro group provides a handle for subsequent reduction and derivatization. The compound exhibits good bench stability and facilitates efficient access to substituted heterocycles relevant to pharmaceutical and agrochemical development.
