    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

This imidazolium-based ionic liquid features a butylsulfonic substituent and a methyl group at the imidazolium core, paired with a hydrogen sulfate anion. It combines high thermal stability with strong solvating power, enabling efficient dissolution of polar and ionic species under standard conditions. The sulfonic acid moiety enhances proton transfer capability, supporting catalytic applications in organic synthesis and electrochemical systems.

Application

1-Butylsulfonic-3-methylimidazolium hydrogensulfate serves as a robust, bench-stable ionic liquid catalyst and reaction medium, enabling efficient acid-catalyzed transformations such as esterifications, acetalizations, and Friedel-Crafts reactions. Its sulfonic acid functionality enhances proton transfer efficiency, while the imidazolium core provides excellent solubility for polar and nonpolar substrates. The hydrogensulfate counterion ensures high thermal stability and facilitates easy product separation, making it ideal for scalable synthesis workflows.
