3939-23-9, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 3939-23-9, Name is 3-Bromo-10H-phenothiazine,introducing its new discovery.
13C Nuclear Magnetic Resonance of Some Derivatives of Phenothiazines, Pyridobenzothiazines and Phenoxazines
Natural abundance 13C NMR studies were carried out on a series of phenothiazines, pyridobenzothiazines and phenoxazines.Chemical shift assignments were made on the basis of models, coupling patterns and aromatic substituent affects.For most of the compounds studied, substituents influence only the carbon chemical shifts of the substituted carbocyclic ring, while the chemical shifts of the unsubstituted ring are essentially the same as those of the parent heterocyclic compound.However, the 10-acetyl and 4′-nitro-10-phenyl groups affect the chemical shifts of several of the carbon atoms in the phenothiazine nucleus.An explanation in terms of resonance interactions between these groups and the N-10 lone-pair electrons is presented.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 3939-23-9, and how the biochemistry of the body works.3939-23-9
