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

3-Methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzonitrile features a boronate ester group paired with a nitrile and methyl substituent on a benzene ring. This combination enables stable coupling in Suzuki-Miyaura reactions, delivering efficient access to functionalized biaryl architectures under standard conditions.

Application

3-Methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzonitrile serves as a versatile boron-containing building block in Suzuki-Miyaura cross-coupling reactions. The pinacol boronate ester group enables efficient coupling with aryl and vinyl halides under mild conditions, while the nitrile and methyl substituents provide orthogonal functional handles for further derivatization. Bench-stable and readily purified by flash chromatography, it facilitates the construction of complex biaryl scaffolds common in pharmaceutical and agrochemical research.
