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-6-methyl-4-nitropyridine features a nitro group at C4 and a chlorine substituent at C2, creating a highly electron-deficient pyridine core. The methyl group at C6 provides steric stabilization, enhancing shelf-life and reactivity control. This compound serves as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly where selective coupling or metal-catalyzed transformations are required.

Application

2-Chloro-6-methyl-4-nitropyridine serves as a versatile building block in medicinal chemistry, enabling efficient construction of pyridine-based heterocycles. The chloro group facilitates nucleophilic substitution under mild conditions, while the nitro and methyl functionalities provide orthogonal handles for further functionalization. Its bench-stable nature and compatibility with standard coupling protocols make it well-suited for modular synthesis workflows.
