sulfinic acids การใช้

• More aggressive oxidants convert cysteine to the corresponding sulfinic acid and sulfonic acid.
• The other reaction product is a sulfinic acid.
• The preparation of sulfinic acids by the oxidation of thiols is difficult due to overoxidation.
• "' Hypotaurine "'is a sulfinic acid that is an intermediate in the biosynthesis of taurine.
• Another commercially important sulfinic acid is hydroxymethyl sulfinic acid, which is usually employed as its sodium salt ( HOCH 2 SO 2 Na ).
• Another commercially important sulfinic acid is hydroxymethyl sulfinic acid, which is usually employed as its sodium salt ( HOCH 2 SO 2 Na ).
• This reaction is exemplified by the conversion of an aryl sulfone into an sulfinic acid by action of " n "-butyllithium:
• Cysteine sulfinic acid lies at a branch-point in cysteine catabolism, where it can follow two pathways resulting in the formation of taurine or sulfate.
• The cysteine sulfinic acid-dependent pathway of taurine metabolism follows the synthesis of hypotaurine ( 2-aminoethane sulfinate ), which is subsequently oxidized to taurine.
• Many other methods have been reported for production of sulfinic acids such as the use tin ( II ) chloride, or the Grignard reagent with sulfur dioxide.
• The reaction of hydroxylamine-" O "-sulfonic acid with metal salts of sulfinic acids in sodium acetate solution produces primary sulfonamides in very good yields.
• Some compounds employed in commercial dechlorinators are : sodium thiosulfate, Sodium hydroxymethanesulfonate ( used in AmQuel ), and Sodium hydroxymethane sulfinic acid ( used in Marineland Bio-safe ).
• Thiourea dioxide is not a dioxide, but instead is a derivative of a sulfinic acid ( RS ( O ) ( OH ), hence the alternative name formamidine sulfinic acid.
• Thiourea dioxide is not a dioxide, but instead is a derivative of a sulfinic acid ( RS ( O ) ( OH ), hence the alternative name formamidine sulfinic acid.
• In the biosynthesis of allicin ( thio-2-propene-1-sulfinic acid S-allyl ester ), cysteine is first converted into alliin ( + S-allyl-L-cysteine sulfoxide ).
• If the nucleophile is water the product is a sulfinic acid, if it is an alcohol the product is a sulfinic ester, if it is a primary or secondary amine the product is a sulfinamide, if it is a thiol the product is a thiosulfinate, while if it is a Grignard reagent the product is a sulfoxide.
• The roots contain sac-like structures that release organic and organosulfur compounds including SO 2, methylsulfinic acid, pyruvic acid, lactic acid, ethanesulfinic acid, propane sulfinic acid, 2-mercaptoaniline, S-propyl propane 1-thiosulfinate, and thioformaldehyde, an elusive and highly unstable compound never before reported to be emitted by a plant.
