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+

Description

1-Phenyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole features a boronate ester group that enables efficient Suzuki-Miyaura cross-coupling reactions. The pyrazole core provides structural rigidity and electronic stability, while the tetramethyl-substituted dioxaborolane enhances moisture tolerance and shelf life. This compound integrates readily into complex molecular architectures under standard conditions.

Application

1-Phenyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole serves as a versatile boron-containing building block for Suzuki-Miyaura cross-coupling reactions. The pyrazole core provides metabolic stability and hydrogen-bonding capacity, while the pinacol boronate ester enables efficient, mild coupling with aryl and heteroaryl halides. Bench-stable and compatible with diverse functional groups, it facilitates rapid access to biaryl-pyrazole scaffolds prevalent in medicinal chemistry and agrochemical research.
