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.

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+

Description

This boronate-functionalized pyrrolopyrazole integrates readily into Suzuki-Miyaura coupling reactions under standard conditions. The tetramethylborolane moiety ensures high stability and compatibility with diverse reaction environments, enabling efficient C–C bond formation in complex molecular architectures.

Application

3-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-5,6-dihydro-4H-pyrrolo[1,2-b]pyrazole serves as a versatile boron-containing building block for Suzuki-Miyaura cross-coupling reactions. Its stable dioxaborolane group enables efficient C–C bond formation under mild conditions, while the dihydropyrrolopyrazole core provides a rigid, nitrogen-rich heterocyclic scaffold relevant to medicinal chemistry and functional materials. The compound exhibits excellent bench stability, minimal air sensitivity, and compatibility with diverse functional groups, facilitating straightforward purification and integration into complex molecular architectures.
