In 2011,Chandrakantha, B.; Isloor, Arun M.; Philip, Reji; Mohesh, M.; Shetty, Prakash; Vijesh, A. M. published 《Synthesis and nonlinear optical characterization of new 1,3,4-oxadiazoles》.Bulletin of Materials Science published the findings.Formula: C8H7BrO2 The information in the text is summarized as follows:
1,3,4-Oxadiazole derivatives containing 2-fluoro-4-methoxy Ph were synthesized by refluxing mixture of acid hydrazide with different aromatic carboxylic acids in phosphorous oxychloride. These newly synthesized compounds were characterized by NMR, mass spectral, and IR spectral studies, and also by C, H, N analyses. The open-aperture z-scan experiment was employed to measure the optical nonlinearity of the samples at 532 nm, using 5 ns laser pulses. The measurements indicate that one of the compounds which contains Br, behaves as an optical limiter at this wavelength, with potential applications in optoelectronics. The experimental part of the paper was very detailed, including the reaction process of 3-Bromo-2-methylbenzoic acid(cas: 76006-33-2Formula: C8H7BrO2)
3-Bromo-2-methylbenzoic acid(cas: 76006-33-2) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals.Formula: C8H7BrO2 The most pervasive is the naturally produced bromomethane.
