4-甲基-3-硝基苯磺酰氯 - Introduction

chloride is an organic compound with the chemical formula C7H6ClNO4S. It is a white to light yellow solid with a peculiar pungent odor.

It is chemically a benzenesulfonyl chloride compound with strong electrophilicity. It can be used as a chlorinating reagent and can react with nucleophiles to give the corresponding substitution products, for example for the synthesis of amino acids, oxamides and other organic compounds. In addition, it can also be used as an intermediate for dyes and pesticides.

chloride can be prepared by reacting benzenesulfonyl chloride with methylating and nitrating reagents. A common synthetic method is the reaction of 4-nitrobenzenesulfonyl chloride with methanol under acidic conditions.

During use, you need to pay attention to the safety of the chloride. This compound is irritating and corrosive and may cause damage to the eyes, skin and respiratory tract. Wear protective gloves, goggles and masks during operation to avoid direct contact or inhalation. It must be used in a well-ventilated place and avoid contact with combustibles and oxidants. If inhaled or ingested by mistake, seek medical attention immediately.
