  • NOVEL AZA BODIPY COMPOUND FOR THE SELECTIVE DETECTION OF NITRITE IONS IN WATER AND A PROCESS FOR PREPARATION THEREOF
    Publication number: 20150291628
    Abstract: The present invention provides aza-BODIPY compound having formula 1 useful for detection of nitrite ions in an aqueous medium. The invention also provides a process for the preparation of aza-BODIPY compound having formula 1. For detecting nitrite ions, a dipstick device made by coating the assay powder of formula 1 in alumina over a thermoplastic or a glass solid support is used. The detection event can be monitored by noting the color change on the surface of the dipstick. Detection event by means of color change is selective for nitrite ions when compared to all other biologically important ions like SO42?, Cl?, HSO3?, CO32?, CH3COO?, NO3?, S2O32?, N3?.
