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-Formylbenzenesulfonyl chloride features a sulfonyl chloride group paired with an aldehyde functionality, enabling dual reactivity for conjugate addition and acylation. This bifunctional electrophile facilitates the synthesis of complex aromatic scaffolds under mild conditions.

Application

4-Formylbenzenesulfonyl chloride serves as a versatile bifunctional building block for the synthesis of sulfonamide-containing scaffolds and heterocycles. Its formyl group enables direct incorporation into Ugi-type multicomponent reactions, while the sulfonyl chloride moiety facilitates rapid coupling with amines or alcohols under mild conditions. The reagent exhibits good bench stability and is compatible with common protecting groups, enabling efficient access to complex molecular architectures in medicinal chemistry and materials science applications.
