The author of 《Infrared spectra of 1,2,3,5-tetrasubstituted benzene derivatives. II》 were Varsanyi, Gyorgy; Sohar, Pal. And the article was published in Acta Chimica Academiae Scientiarum Hungaricae in 1973. HPLC of Formula: 37908-97-7 The author mentioned the following in the article:
A detailed interpretation is given of the ir spectra of 35 1,2,3,5-tetrasubstituted benzenes containing light atoms (at. weight <20) in positions 2 and 5 and heavy atoms (at. weight >20) in positions 1 and 3. Correlations were established between the intensity and frequency of the spectral bands, and the influence of substituents on the electron distribution. The coupling of certain vibrations having identical symmetry was demonstrated and the association structure of the individual compounds was established. The results came from multiple reactions, including the reaction of 3,5-Dichloro-4-methoxybenzoic acid(cas: 37908-97-7HPLC of Formula: 37908-97-7)
3,5-Dichloro-4-methoxybenzoic acid(cas: 37908-97-7) belongs to organochlorine compounds. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.HPLC of Formula: 37908-97-7
