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

5-Chloro-2,4-difluoropyridine features a highly reactive pyridine core with strategically positioned halogen substituents. This electron-deficient heterocycle enables efficient cross-coupling and nucleophilic substitution under mild conditions. The orthogonal reactivity of chlorine and fluorine allows for sequential functionalization in complex molecule synthesis. Bench-stable and moisture-tolerant, it serves as a key building block in pharmaceutical and agrochemical development.

Application

5-Chloro-2,4-difluoropyridine serves as a versatile building block in medicinal chemistry, enabling efficient construction of heterocyclic scaffolds through nucleophilic substitution. Its orthogonal reactivity allows selective functionalization at the C5 position while preserving fluorine handles for further derivatization. The compound exhibits excellent bench stability and compatibility with standard coupling protocols, facilitating integration into multi-step synthesis workflows for API development.
