Benzenesulfinic acid, 4-methyl-, methyl ester

Description:
Benzenesulfinic acid, 4-methyl-, methyl ester, also known by its CAS number 672-78-6, is an organic compound characterized by the presence of a sulfinic acid group attached to a benzene ring that has a methyl substituent at the para position. This compound is typically a colorless to pale yellow liquid with a distinct aromatic odor. It is soluble in organic solvents and exhibits moderate stability under standard conditions. The methyl ester functional group contributes to its reactivity, allowing it to participate in various chemical reactions, including nucleophilic substitutions and esterification processes. Benzenesulfinic acids are known for their applications in organic synthesis, particularly in the preparation of sulfonamides and other sulfonic derivatives. Additionally, the presence of the methyl group can influence the compound's physical properties, such as boiling point and solubility. Safety data indicates that, like many sulfinic acids, it should be handled with care due to potential irritant properties.
