Busev, A. I. published the artcileSpectroscopic study of the reaction products of Rhodamine 6Zh with naftamon during extraction by benzene, Product Details of C28H29NO4, the publication is Izvestiya Vysshikh Uchebnykh Zavedenii, Khimiya i Khimicheskaya Tekhnologiya (1974), 17(9), 1367-70, database is CAplus.
Reaction products of the dye Rhodamine 6Zh (I) [7325-85-1] with Naftamon (II) [3818-50-6], and the dye itself were extracted with C6H6, and the spectra obtained from the extracts in the region 17,000-22,000 cm-1 were split into gauss constituents. Four gauss peaks were found in the extract corresponding to monomeric and dimeric forms of ionic associates of I with II and traces of the dye.
Izvestiya Vysshikh Uchebnykh Zavedenii, Khimiya i Khimicheskaya Tekhnologiya published new progress about 3818-50-6. 3818-50-6 belongs to alcohols-buliding-blocks, auxiliary class Anti-infection,Antiparasitic, name is N-Benzyl-N,N-dimethyl-2-phenoxyethanaminium 3-hydroxy-2-naphthoate, and the molecular formula is C28H29NO4, Product Details of C28H29NO4.
