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.

Description

Pyridinium trifluoromethanesulfonate delivers a robust, moisture-tolerant source of triflic acid under mild conditions. This bench-stable salt features a pyridinium cation paired with a highly stable triflate anion, enabling efficient proton transfer in synthetic transformations. It integrates seamlessly into catalytic systems requiring strong yet controllable acidity, particularly in C–H functionalization and esterification reactions.

Application

Pyridinium trifluoromethanesulfonate serves as a highly effective catalyst for acid-promoted transformations, enabling efficient O- and N-arylations, glycosylations, and deprotection reactions under mild conditions. Its bench-stable solid form facilitates handling, while the triflate anion ensures high catalytic activity with excellent functional group tolerance across diverse synthetic workflows.
