The sulfonate ion. In organosulfur chemistry, a sulfonate is a salt, anion or ester of a sulfonic acid. Its formula is R−S(=O) 2 −O −, containing the functional group −S(=O) 2 −O −, where R is typically an organyl group, amino group or a halogen atom. Sulfonates are the conjugate bases of sulfonic acids.
TMSOTf is quite sensitive toward hydrolysis: (CH 3) 3 SiO 3 SCF 3 + H 2 O → (CH 3) 3 SiOH + HO 3 SCF 3. It is far more electrophilic than trimethylsilyl chloride.. Related to its tendency to hydrolyze, TMSOTf is effective for silylation of alcohols: [2]

The Sullivan reaction is a chemical test used for detecting the presence of cysteine or cystine in proteins. A red colour appears when a protein with cysteine or cystine is heated with sodium 1,2-naphthoquinone-4-sulfonate (Folin's reagent) and sodium dithionite under alkaline conditions.
Folin's reagent or sodium 1,2-naphthoquinone-4-sulfonate is a chemical reagent used as a derivatizing agent to measure levels of amines and amino acids. [1] The reagent reacts with them in alkaline solution to produce a fluorescent material that can be easily detected.
In organic synthesis, PPTS is used as a weakly acidic catalyst, providing an organic soluble source of pyridinium (C 5 H 5 NH +) ions.For example, PPTS is used to deprotect silyl ethers or tetrahydropyranyl ethers when a substrate is unstable to stronger acid catalysts.
8-Anilinonaphthalene-1-sulfonic acid (ANS), also called 1-anilino-8-naphthalenesulfonate, is an organic compound containing both a sulfonic acid and an amine group. This compound is used as a fluorescent molecular probe. [1]
Methyl fluorosulfonate, also known as magic methyl, is the organic compound with the formula FSO 2 OCH 3.It is a colorless liquid that is used as a strong methylating agent in organic synthesis.
