Methyl 2-methylbutyrate. Expanded sweep widths of the downfield methyl resonances are shown to the left of the corresponding spectrum. Inspired by Nature: A diverse range of products, all meeting our stringent commitment to quality. Data compiled by: NIST Mass Spectrometry Data Center, William E. Wallace, director Similarly, for the 3-methyl-3-phenyl-2-pentanone, nonequivalence is observed for the acyl-methyl (R 5.78 ppm, S 5.68 ppm) and 3-methyl protons (S 3.90 ppm, R 3.83 ppm). Fatty acid methyl esters are compounds containing a fatty acid that is esterified with a methyl group. Ester names are derived from the parent alcohol and the parent acid, where the latter may be organic or inorganic. Vapor-phase methyl n-butyrate is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals (SRC); the half-life for this reaction in air is estimated to be 5 days (SRC), calculated from its rate constant of 3X10-12 cu cm/molecule-sec at 25 °C (3).
