Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels. 37830-90-3. In a patent£¬Which mentioned a new discovery about 37830-90-3, molcular formula is C5H6O3, introducing its new discovery.
PREPARATION 1 4-Bromomethyl-5-methyl-2-oxo-1,3-dioxole To a stirred solution of 3.0 g of 4,5-dimethyl-2-oxo-1,3-dioxole in 100 ml of carbon tetrachloride was added 4.63 g of N-bromosuccinimide. The resulting solution was heated under reflux and irradiated for 15 minutes. The reaction mixture was cooled to 0¡ã-5¡ã C., filtered and evaporated to give the title product. The NMR spectrum (CDCl3) showed absorptions at 2.05 (5percent of starting material), 2.18 (3H, s), 4.30 (2H, s) and 4.35 (5percent of dibromo compound) ppm downfield from tetramethylsilane. The IR spectrum showed an absorption at 5.49 microns.
Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield,they are the focus of active research.37830-90-3, you can also check out more blogs about37830-90-3
