    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

Biphenyl-4,4'-diboronic acid bis(pinacol) ester offers robust stability and ease of handling in cross-coupling reactions. This bifunctional boronate ester integrates seamlessly into Suzuki-Miyaura couplings, enabling efficient C–C bond formation under mild conditions. The pinacol moiety enhances shelf life and moisture tolerance, while the biphenyl scaffold provides defined electronic properties for predictable reactivity.

Application

Biphenyl-4,4'-diboronic acid bis(pinacol) ester serves as a stable, bench-ready building block for Suzuki-Miyaura cross-coupling reactions. Its dual boronate ester functionality enables efficient homocoupling or sequential coupling with aryl halides and pseudohalides. The pinacol protection enhances stability and simplifies purification, making it ideal for constructing biaryl scaffolds in medicinal chemistry and materials science workflows.
