CAS 57057-80-4: Ethyl (2S)-2-[[(4-methylphenyl)sulfonyl]oxy]propanoate

Description: Ethyl (2S)-2-[[(4-methylphenyl)sulfonyl]oxy]propanoate, with the CAS number 57057-80-4, is an organic compound characterized by its ester functional group, which is derived from the reaction of an alcohol (ethyl alcohol) and a carboxylic acid. This compound features a chiral center, indicated by the (2S) configuration, which contributes to its stereochemical properties. The presence of a sulfonate group, specifically the 4-methylphenylsulfonyl moiety, enhances its reactivity and solubility in various organic solvents. Ethyl (2S)-2-[[(4-methylphenyl)sulfonyl]oxy]propanoate is typically a colorless to pale yellow liquid, exhibiting moderate volatility and stability under standard conditions. Its applications may include use as an intermediate in organic synthesis, particularly in the development of pharmaceuticals or agrochemicals, due to its ability to participate in nucleophilic substitution reactions. Safety data should be consulted for handling and storage, as with all chemical substances, to ensure proper precautions are taken.
