In the hydrated title salt, C 7 H 12 N 5 S 2 + ·Cl − ·H O, asymmetric unit comprises one 2-amino-5-{(1 E )-1-[(carbamothioylamino)imino]ethyl}-4-methyl-1,3-thiazol-3-ium cation, chloride anion and water molecule of crystallization. The cation is nearly flat (r.m.s. deviation non-H atoms 0.0814 Å), with largest 0.1484 (14) Å observed for methyl atoms. crystal, cations are linked by O—H...Cl, N—H...

Abstract Ozone is widely used in daily life, but studies have shown that O 3 can damage human trachea and lungs, leading to diseases such as asthma, emphysema, bronchitis. Therefore, it of great significance develop a simple efficient detection method for monitoring living cells. In this study, 3-(but-3-en-1-yl)-2-(7-(but-3-en-1-yloxy)-2-oxo-2H-chromen-3-yl)benzo[d]thiazol-3-ium (BCT) new type ...
