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
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

This boronate ester features a tetrahydro-2H-pyran-4-yl protecting group that enhances stability and solubility in polar organic solvents. It integrates readily into Suzuki-Miyaura cross-coupling reactions under standard conditions, offering reliable performance in complex molecule assembly workflows.

Application

4,4,5,5-Tetramethyl-2-(tetrahydro-2H-pyran-4-yl)-1,3,2-dioxaborolane serves as a stable, bench-ready boronate building block for Suzuki-Miyaura cross-coupling reactions. The tetrahydro-2H-pyran-4-yl group provides orthogonal protection and enhanced solubility, while the tetramethyl-substituted dioxaborolane core ensures high reactivity and resistance to hydrolysis. This compound facilitates efficient coupling with aryl, vinyl, and heteroaryl halides under mild conditions, enabling rapid access to complex molecular architectures in medicinal chemistry and materials synthesis.
