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

(E)-4-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)but-3-en-2-ol features a boronate ester group conjugated to an (E)-configured enol double bond, enabling selective cross-coupling under mild conditions. The tetramethyl-substituted dioxaborolane moiety imparts enhanced stability and moisture tolerance, while the enol functionality supports direct integration into complex molecular architectures without requiring protection.

Application

(E)-4-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)but-3-en-2-ol serves as a versatile boron-containing building block for Suzuki-Miyaura cross-coupling reactions. The vinyl boronate moiety enables efficient C–C bond formation under mild conditions, while the (E)-configured double bond ensures stereochemical fidelity in downstream transformations. Its bench-stable tetramethylboronate group offers excellent functional group tolerance and simplifies purification. This compound functions as a key intermediate in the synthesis of conjugated dienes and complex heterocyclic scaffolds relevant to medicinal chemistry and materials science.
