    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

4-Aminobenzene-1-sulfonyl fluoride is a bench-stable, moisture-tolerant reagent featuring a reactive sulfonyl fluoride group paired with an electron-rich para-amino substituent. This combination enables selective labeling of nucleophilic residues in proteins and facilitates the synthesis of sulfonamide-based probes for chemical biology applications.

Application

4-Aminobenzene-1-sulfonyl fluoride serves as a versatile sulfonylating agent in medicinal chemistry, enabling efficient introduction of sulfonamide moieties under mild conditions. Its bench-stable nature and compatibility with diverse functional groups facilitate straightforward incorporation into bioactive scaffolds, particularly in kinase inhibitor development and heterocyclic synthesis.
