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

2,4-Dichloro-6-methylpyridine serves as a key heterocyclic scaffold in medicinal chemistry and agrochemical synthesis. The electron-deficient pyridine ring, flanked by two chlorine substituents and a methyl group at the 6-position, enables selective coupling reactions. This configuration enhances reactivity in cross-coupling processes while maintaining stability under standard reaction conditions.

Application

2,4-Dichloro-6-methylpyridine serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling selective functionalization at the 3- and 5-positions via palladium-catalyzed cross-coupling. Its ortho-chlorine atoms exhibit high reactivity in nucleophilic substitution reactions, while the methyl group provides a stable handle for further derivatization. The compound demonstrates excellent bench stability and compatibility with standard purification methods, facilitating efficient incorporation into complex heterocyclic scaffolds and API intermediates.
