    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-Boronoisophthalic acid features a rigid aromatic core with strategically positioned boronic acid and carboxylic acid groups, enabling efficient conjugation in Suzuki coupling reactions. This dual-functional scaffold integrates seamlessly into bioconjugation workflows and materials synthesis under standard conditions.

Application

5-Boronoisophthalic acid serves as a versatile building block in transition-metal-catalyzed coupling reactions, particularly Suzuki-Miyaura cross-couplings. Its ortho-dicarboxylic acid motif provides enhanced solubility and facilitates purification, while the boronic acid group enables reliable C–C bond formation under mild conditions. The molecule exhibits good bench stability and functional group tolerance, making it well-suited for modular synthesis of complex aromatic systems and biologically relevant scaffolds.
