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.

Type	HazMat Fee

Description

This boronate ester features a triphenylenyl group integrated at the 2-position, enhancing electronic delocalization and stability. The tetramethyl-substituted dioxaborolane ring ensures excellent bench stability and moisture tolerance, enabling reliable use in Suzuki-Miyaura cross-coupling reactions under standard conditions.

Application

4,4,5,5-Tetramethyl-2-(triphenylen-2-yl)-1,3,2-dioxaborolane serves as a stable, bench-ready boron source for Suzuki-Miyaura cross-coupling reactions. Its triphenylenyl moiety imparts enhanced planarity and electronic stability, enabling efficient coupling with aryl halides and pseudohalides under standard conditions. The tetramethyl substitution ensures excellent shelf life and ease of handling, while the dioxaborolane ring facilitates clean reaction profiles and straightforward purification—ideal for constructing complex biaryl scaffolds in medicinal chemistry and materials science applications.
