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+

Description

Dimesityliodonium trifluoromethanesulfonate serves as a stable, bench-ready hypervalent iodine reagent for C–H functionalization and cross-coupling reactions. Featuring two mesityl groups that enhance solubility and reduce decomposition, this reagent enables efficient transfer of electrophilic iodonium species under mild conditions.

Application

Dimesityliodonium trifluoromethanesulfonate serves as a stable, bench-ready source of electrophilic iodine(III) for C–H functionalization and arylation reactions. Its mesityl groups confer excellent solubility and thermal stability, while the triflate counterion enables efficient transmetalation in transition-metal-catalyzed transformations. Widely used in modern synthetic protocols, it facilitates direct arylation of heterocycles, alkenes, and arenes under mild conditions, offering high functional group tolerance and straightforward purification.
