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

Azetidine-1-sulfonyl chloride delivers a highly reactive sulfonyl group tethered to a strained four-membered ring, enabling efficient incorporation into complex molecular architectures. This bench-stable reagent facilitates rapid derivatization in synthetic and medicinal chemistry workflows, particularly for targeted protein labeling and bioconjugation applications.

Application

Azetidine-1-sulfonyl chloride serves as a versatile electrophilic sulfonating agent, enabling efficient introduction of the sulfonyl group into diverse substrates. Its strained four-membered ring enhances reactivity while maintaining bench stability under anhydrous conditions. The reagent facilitates direct sulfonation of amines and heterocycles, offering high functional group tolerance and straightforward purification. It functions as a key building block in the synthesis of sulfonamide-containing scaffolds relevant to medicinal chemistry and catalytic systems.
