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+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+
Inaccessible (Haz class 6.1 or 9), International	$108.00+

Description

(Z)-2-(2-Ethoxyvinyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane is a bench-stable boronate ester featuring a stereodefined (Z)-ethenylic vinylboronate moiety. This configuration enhances coupling efficiency in palladium-catalyzed cross-coupling reactions. The tetramethyl-substituted dioxaborolane ring provides excellent stability and moisture tolerance. It integrates readily into complex molecule synthesis under standard conditions.

Application

(Z)-2-(2-Ethoxyvinyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane serves as a stable, bench-ready boron building block for Suzuki-Miyaura cross-coupling reactions. Its (Z)-configured vinylborane moiety enables stereoselective introduction of functionalized alkenyl groups into complex molecular architectures. The tetramethyl-substituted dioxaborolane ring enhances air and moisture stability, facilitating handling and purification. This reagent functions effectively in late-stage diversification and heterocycle synthesis, offering predictable regiochemistry and high compatibility with diverse coupling partners.
