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-Chloro-2-methylpyridine is a heterocyclic building block featuring a chlorine atom at the 3-position and a methyl group at the 2-position of the pyridine ring. This configuration imparts enhanced electrophilicity and regioselectivity in cross-coupling reactions, enabling efficient integration into pharmaceutical intermediates and functional materials under standard conditions.

Application

3-Chloro-2-methylpyridine serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling efficient functionalization at the pyridine ring. Its ortho-chloro and methyl substituents provide complementary sites for transition-metal-catalyzed coupling reactions and electrophilic substitution, with good bench stability and straightforward purification. Functions effectively in Suzuki-Miyaura, Buchwald-Hartwig, and nucleophilic displacement protocols, offering reliable access to substituted heterocyclic scaffolds common in drug discovery pipelines.
