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-4-methyl-5-nitropyridine features a pyridine core functionalized with chlorine, methyl, and nitro groups at the 2-, 4-, and 5-positions respectively. This electron-deficient heterocycle serves as a key intermediate in medicinal chemistry, enabling direct coupling reactions through the chloro group while the nitro moiety facilitates downstream transformations. The methyl substituent enhances solubility and modulates reactivity.

Application

2-Chloro-4-methyl-5-nitropyridine serves as a versatile building block in medicinal chemistry, enabling palladium-catalyzed cross-coupling reactions due to its reactive chloropyridine functionality. The ortho-chloro group facilitates efficient C–C and C–N bond formation under standard conditions, while the methyl and nitro substituents provide steric and electronic modulation. This compound exhibits good bench stability and is compatible with common protecting group strategies, making it valuable for constructing heterocyclic scaffolds in API development.
