Yang, Shizhong published the artcileA newly developed luminescent label – synthesis and properties of 6-coumarinsulfonyl chloride, Related Products of chlorides-buliding-blocks, the publication is Fenxi Huaxue (1992), 20(2), 202-4, database is CAplus.
The title compound (I) was prepared by reaction if coumarin with ClSO3H. Effects of pH, lighting and surfactant on the fluorescence properties of its aqueous solution, and the reactiveness to amino acids etc. are studied. The results show that both basic condition and enough lighting are necessary conditions for obtaining stabilized and strong fluorescence from aqueous solution of I, and quaternary ammonium salt surfactant can enhance its fluorescence intensity. It also showed that this simple derivative of coumarin can be used as a luminescence labeling reagent for amino acid, amines etc. which has reactivity with SO2Cl group.
