    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

1-Ethyl-2,3-dimethylimidazolium tetrafluoroborate is a bench-stable ionic liquid featuring a cation with steric shielding from methyl groups and a weakly coordinating tetrafluoroborate anion. This combination enhances solubility for polar substrates while maintaining thermal resilience. The imidazolium core enables efficient phase transfer in catalytic systems, particularly in metal-free cross-coupling reactions.

Application

1-Ethyl-2,3-dimethylimidazolium tetrafluoroborate serves as a stable, bench-friendly ionic liquid salt that functions as a versatile catalyst and reaction medium in transition metal-catalyzed couplings and C–H functionalization processes. Its imidazolium core enables strong stabilization of reactive intermediates, while the tetrafluoroborate anion supports low volatility and ease of handling. The compound exhibits excellent functional group tolerance and facilitates efficient transformations under mild conditions, making it suitable for scalable synthesis workflows.
