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

2,3,5,6-Tetrachloropyridine is a highly chlorinated pyridine derivative featuring four chlorine atoms at the 2-, 3-, 5-, and 6-positions of the aromatic ring. This electron-deficient heterocycle serves as a key intermediate in the synthesis of pharmaceuticals, agrochemicals, and functionalized materials. Its stability under standard conditions enables reliable use in cross-coupling and nucleophilic substitution reactions.

Application

2,3,5,6-Tetrachloropyridine serves as a versatile electrophilic building block in heterocyclic synthesis, enabling selective functionalization at nitrogen and ortho positions. Its high reactivity facilitates nucleophilic substitution under mild conditions, making it valuable for constructing complex pyridine-based scaffolds. The molecule exhibits good bench stability and is compatible with standard purification techniques, supporting its use in medicinal chemistry and process development workflows.
