Fluorescent chromophores with long-wavelength emission has arisen in conjunction with single-mol. spectroscopy of biomols. where most traditional dyes lack the required fluorescence quantum yield and photostability or whose performance is hampered by aggregation of their extended-conjugated cores. Fluorescence imaging of single mols. is a powerful technique in which subtle characteristics of the structure and dynamics of complex condensed materials are revealed that are otherwise hidden in ensemble measurements. This study involved multiple reactions and reactants, such as 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0Application In Synthesis of 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one).
3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0) belongs to thiazole derivatives. Thiazoles frequently appear in peptide studies. Thiazoles can also be used as protected formyl groups, which can be released in later stages of complex natural product synthesis. The nitrogen in thiazole is sp2 hybridized and the lone pair of electrons localized on the nitrogen is less reactive due to increased aromatic character and decreased basicity. It is protonated and alkylated/acylated at nitrogen forming hydrochloride and quaternary thiazolium salt.Application In Synthesis of 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one
