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

2-Fluoro-5-(trifluoromethyl)benzene-1-sulfonyl chloride features a highly electron-deficient aromatic ring stabilized by orthogonal fluorine and trifluoromethyl substituents, enabling selective sulfonylation under mild conditions. This bench-stable reagent integrates efficiently into complex molecule synthesis, delivering robust functional group transformation with minimal side reactivity.

Application

2-Fluoro-5-(trifluoromethyl)benzene-1-sulfonyl chloride serves as a versatile electrophilic sulfonating agent, enabling efficient introduction of the trifluoromethyl-substituted sulfonyl group into diverse substrates. Its high reactivity facilitates clean derivatization of amines and alcohols under mild conditions, with excellent bench stability and straightforward purification. This reagent functions effectively in the synthesis of functionalized aryl sulfonamides and sulfonates, offering robust compatibility across standard synthetic workflows.
