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

2,6-Dimethoxybenzenesulfonyl chloride features a sulfonyl chloride group flanked by two methoxy substituents at the 2 and 6 positions of the benzene ring. This electron-rich, sterically hindered architecture enhances reactivity while improving stability under standard handling conditions. The compound serves as a selective sulfonating agent in synthetic transformations, enabling efficient incorporation of sulfonyl moieties into complex molecular frameworks.

Application

2,6-Dimethoxybenzenesulfonyl chloride serves as a robust sulfonylating agent for the synthesis of sulfonamide derivatives and sulfonate esters. Its ortho-dimethoxy substitution enhances electrophilicity while improving solubility in polar organic solvents. The compound exhibits excellent bench stability and facilitates clean reactions with amines and alcohols under mild conditions, enabling efficient access to functionalized intermediates for medicinal chemistry and materials science applications.
