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-4-fluorophenylboronic acid features a boronic acid group flanked by chlorine and fluorine substituents, enabling efficient cross-coupling under standard conditions. This electron-deficient arylboronic acid delivers high reactivity in Suzuki-Miyaura reactions, particularly with challenging substrates. The ortho-chloro and para-fluoro pattern enhances stability and selectivity, streamlining access to complex fluorinated biaryl architectures.

Application

2-Chloro-4-fluorophenylboronic acid serves as a versatile building block in Suzuki-Miyaura coupling reactions, enabling efficient C–C bond formation under mild conditions. Its orthogonal reactivity allows selective functionalization in the presence of other halogens, while its bench-stable solid form facilitates handling and purification. Widely used in medicinal chemistry and agrochemical synthesis, it provides access to substituted aryl scaffolds with enhanced metabolic stability and targeted bioactivity.
