Methyl nonadecanoate (cas: 1731-94-8) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

A Comprehensive Evaluation of the Density of Neat Fatty Acids and Esters was written by Knothe, Gerhard;Steidley, Kevin R.. And the article was included in Journal of the American Oil Chemists’ Society in 2014.Quality Control of Methyl nonadecanoate The following contents are mentioned in the article:

D. is one of the most important phys. properties of a chem. compound, affecting numerous applications. An application in the case of fatty acid esters (biodiesel) is that d. is specified in some biodiesel standards In the present work, the d. of fatty acid Me, Et, Pr, and Bu esters as well as triacylglycerols in the C8-C24 range was determined in the range of 15-40 °C with a densitometer utilizing the oscillating U-tube technique. Literature data on d. are compiled and compared, showing that data for these compounds are incomplete with discrepancies existing in some cases. Besides known effects such as d. decreasing with increasing chain length and increasing saturation, it is shown that trans fatty compounds exhibit lower d. than cis fatty compounds D. data for several saturated odd-numbered, C18, as well as C20 and C22 polyunsaturated fatty esters are reported for the first time. The d. contribution of compounds with high m.ps. is predicted. An equation is given for the calculation of the d. of mixtures This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Quality Control of Methyl nonadecanoate).
