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

6-Chloro-3-pyridinesulfonyl chloride features a chlorinated pyridine scaffold paired with a reactive sulfonyl chloride group, enabling direct conjugation in synthetic transformations. This electrophilic moiety facilitates efficient coupling under mild conditions, delivering stable heterocyclic architectures ideal for pharmaceutical intermediates and functional materials.

Application

6-Chloro-3-pyridinesulfonyl chloride serves as a versatile electrophilic sulfonylating agent, enabling efficient introduction of the 6-chloro-3-pyridylsulfonyl group into diverse substrates. Its reactivity facilitates rapid functionalization of nucleophiles such as amines and alcohols under mild conditions, offering high yields and excellent bench stability. The chloropyridine moiety enhances compatibility with subsequent cross-coupling reactions, making it a valuable building block for medicinal chemistry campaigns and heterocyclic scaffold elaboration.
