2-(4-Nitrophenoxy)acetyl chloride

Description:
2-(4-Nitrophenoxy)acetyl chloride, with the CAS number 20142-88-5, is an organic compound characterized by its acetyl chloride functional group and a nitrophenoxy substituent. This compound typically appears as a yellow to brownish liquid and is known for its reactivity, particularly in acylation reactions. The presence of the nitro group enhances its electrophilic character, making it a useful intermediate in organic synthesis, especially in the preparation of various pharmaceuticals and agrochemicals. It is soluble in organic solvents such as dichloromethane and ether but is generally insoluble in water due to its hydrophobic nature. As an acyl chloride, it is sensitive to moisture and can react vigorously with water, releasing hydrochloric acid and forming the corresponding carboxylic acid. Safety precautions are essential when handling this compound, as it can be corrosive and irritating to the skin, eyes, and respiratory system. Proper storage in a cool, dry place, away from moisture and incompatible substances, is crucial to maintain its stability and reactivity.
