While the job of a research scientist varies, most chemistry careers in research are based in laboratories, where research is conducted by teams following scientific methods and standards.503-74-2, Name is 3-Methylbutanoic acid, SMILES is CC(C)CC(O)=O, in an article , author is Matos, MAR, once mentioned of 503-74-2, Quality Control of 3-Methylbutanoic acid.
The standard (pdegrees = 0.1 MPa) molar enthalpy of formation of liquid anthranil was measured at T = 298.15 K by static bomb calorimetry and the standard molar enthalpy of vaporization at T = 298.15 K was obtained using Calvet microcalorimetry. These values were used to derive the standard molar enthalpy of formation of anthranil in the gaseous phase. Thermochemical and quantum chemical comparisons were made to interrelate anthranil and its isomers, 1,2-benzisoxazole, benzoxazole and 2-cyanophenol, and the monocyclic heterocycles, isoxazole and oxazole. Comparisons with benzofurazan and isobenzofuran were also made. Additionally nucleus-independent chemical shifts were used as an aromaticity index. (C) Wiley-VCH Verlag GmbH & Co.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 503-74-2 is helpful to your research. Quality Control of 3-Methylbutanoic acid.
