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

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+

Description

This boronate ester features a (E)-configured pentenyl chain with a terminal vinyl group, enabling selective cross-coupling reactions. The tetramethyl-substituted dioxaborolane ring ensures high stability and moisture tolerance, while the chlorine atom provides a handle for further functionalization. Designed for efficient Suzuki-Miyaura coupling under mild conditions, this reagent integrates readily into complex molecule synthesis workflows.

Application

(E)-2-(5-Chloropent-1-en-1-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane serves as a versatile boron-containing building block for Suzuki-Miyaura cross-coupling reactions. The terminal vinylboronate functionality enables efficient coupling with aryl and vinyl halides under mild conditions, while the (E)-configured alkene and tetramethyl substitution enhance stability and reduce protodeboronation. Its bench-stable nature and compatibility with diverse functional groups make it ideal for constructing complex molecular architectures in medicinal chemistry and materials synthesis.
