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-6-fluoro-2-methoxyphenylboronic acid features a boronate moiety integrated into a halogenated aromatic scaffold, enabling efficient cross-coupling under standard conditions. The electron-deficient ring enhances reactivity in Suzuki-Miyaura transformations, while the methoxy group improves solubility and stability. This bench-stable reagent streamlines access to functionalized biaryl architectures in medicinal chemistry and materials synthesis.

Application

3-Chloro-6-fluoro-2-methoxyphenylboronic acid serves as a versatile building block in Suzuki-Miyaura cross-coupling reactions, enabling efficient construction of biaryl architectures. Its ortho-halogenated and methoxy-substituted aryl framework provides predictable regiochemistry and enhanced stability under standard reaction conditions. The boronic acid functionality facilitates mild coupling with aryl halides and pseudohalides, offering excellent functional group tolerance and straightforward purification, making it a practical choice for medicinal chemistry and process development workflows.
