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-5-fluoropyridine is a heterocyclic building block featuring complementary halogen substituents at adjacent positions on the pyridine ring. This electron-deficient scaffold enables direct functionalization in cross-coupling reactions and serves as a key intermediate in pharmaceutical synthesis. Its bench-stable nature supports reliable handling under standard conditions.

Application

3-Chloro-5-fluoropyridine serves as a versatile building block in medicinal chemistry, enabling palladium-catalyzed cross-coupling reactions due to its orthogonal halogen reactivity. The chloro and fluoro substituents offer distinct reaction handles for sequential functionalization, while the pyridine core provides a stable, electron-deficient scaffold suitable for drug-like molecule synthesis. Its bench-stable solid form facilitates handling and purification in standard laboratory workflows.
