p-Toluenesulfinic acid（Cat No.:L045341）is an aromatic sulfinic acid derivative, with a methyl group (-CH₃) attached to the para position of a benzene ring, and a sulfinic acid group (-SO₂H) attached to the ring. It is commonly used as a reagent in organic synthesis, particularly in the formation of sulfonate esters and in reactions requiring sulfur-based intermediates. p-Toluenesulfinic acid is a valuable tool in the synthesis of pharmaceuticals, agrochemicals, and other specialty chemicals. It also plays a role in the preparation of chiral compounds, owing to its ability to undergo selective transformations.
