    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

Sulfur trioxide-trimethylamine complex acts as a reagent for sulfonation and sulfamation reactions. It is used as a reactant for the synthesis of sulfate-conjugated resveratrol metabolites and chitooligosaccharides. It is used in association with dodecyl thioglycopyranoside, which acts as a surfactant for enantiomeric separation. Further, it acts as a nucleophile used for the preparation of alfa-tosyloxy ketones.

Application

1-Ethyl-3-methyl-1H-imidazol-3-ium tetrachloroferrate(III) serves as a stable, bench-ready ionic liquid catalyst for electrophilic functionalization reactions. Its imidazolium cation enables efficient activation of substrates in Friedel–Crafts-type processes, while the tetrachloroferrate(III) anion provides strong Lewis acidity under mild conditions. The salt exhibits excellent functional group tolerance and facilitates clean reaction profiles with straightforward purification, making it well-suited for scalable synthesis of complex heterocycles and aromatic derivatives.
