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

This boronate moiety features a strategically positioned chloro and fluoro substituent on the pyridine ring, enabling selective cross-coupling reactions under mild conditions. The electron-deficient heterocycle enhances reactivity in Suzuki-Miyaura transformations, while the bench-stable nature facilitates handling in synthetic workflows.

Application

(3-Chloro-2-fluoropyridin-4-yl)boronic acid serves as a versatile building block in Suzuki-Miyaura cross-coupling reactions, enabling efficient construction of functionalized pyridine scaffolds. Its stability under ambient conditions and compatibility with diverse reaction partners facilitate straightforward access to substituted heterocycles. The ortho-halogen substituents allow for sequential functionalization or further derivatization, enhancing its utility in medicinal chemistry and materials science applications.
