white to beige crystalline powder | [Uses]
1-Naphthalenesulfonyl chloride has been used in the preparation of 5?-O-naphthaleneiulfonyldeoxyuridine and 1-sulfonylindazole derivatives. The derivatives of this compound is used for quantitative metabolome analysis New set of isotope reagents, 12C4-, 12C213C2-, and 13C4-5-diethylamino-naphthalene-1-sulfonyl chloride (DensCl), in combination with liquid chromatography Fourier-transform ion cyclotron resonance mass spectrometry (LC-FTICR-MS) is used for improved analysis of the amine- and phenol-containing submetabolome. | [General Description]
1-Naphthalenesulfonyl chloride undergoes desulfitative carbonylative Stille cross-coupling reaction with tinglucal derivative. | [Purification Methods]
If the IR indicates the presence of OH, then treat it with an equal weight of PCl5 and heat it at ca 100o for 2hours, cool and pour onto ice + H2O, stir well and filter off the solid. Wash the solid with cold H2O and dry the solid in a vacuum desiccator over P2O5 + solid KOH. Extract the solid with pet ether (b 40-60o), filter off any insoluble solid and cool. Collect the crystalline sulfonyl chloride and recrystallise it from dry Et2O, pet ether or *C6H6/pet ether. If large quantities are available, then it can be distilled under high vacuum. [Fierz-Davaid & Weissenbach Helv Chim Acta 3 2312 1920.] The sulfonamide crystallises from EtOH (m 150.5o) or H2O (m 153o). [Beilstein 11 H 175, 11 II 93, 11 IV 383.] |
