Description and Uses

Dithiazanine iodide is a green, needle-likecrystalline solid which decomposes at 248℃. Sulfur-likeodor. Molecular weight= 519.51. Melting point 5 225℃;Hazard Identification (based on NFPA-704 M RatingSystem): Health 3, Flammability 0, Reactivity 1. Insolublein water.

It is employed as a solvent soluble laser dye. DTDCi is used as fluorescent contrast agent in three-dimensional fluorescence lifetime tomography and as a dye for rapid genetic screening. It is a potential sensitive probe useful for fluorometric analysis of transferable membrane pores and effects of membrane potential on Na cotransports in eel intestinal brush-border membrane vesicles.
