Methyl heptanoate (cas: 106-73-0) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. 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 new stationary phase for capillary gas chromatography: Calix[4]resorcinarene functionalized with imidazolium cationic units was written by Shuai, Xiaomin;Cai, Zhiqiang;Zhao, Xinyu;Chen, Yujie;Zhang, Qian;Ma, Ziwei;Hu, Junjie;Sun, Tao;Hu, Shaoqiang. And the article was included in Chromatographia in 2021.Application In Synthesis of Methyl heptanoate The following contents are mentioned in the article:

A novel calix[4]resorcinarene-based ionic liquid (C4RA-2IL) was synthesized, structurally characterized, and statically coated on capillary column as stationary phase for capillary gas chromatog. (GC). The column efficiency of the C4RA-2IL column is 3345 plates m-1, which are determined by n-dodecane at 120°C. Based on its McReynolds constants, the C4RA-2IL column showed moderate polarity. Particularly, the C4RA-2IL column show high separation performance for a wide range of analytes and some difficult separation of meta/para-isomers. Moreover, it exhibited excellent selectivity for critical aromatic isomers of chloroaniline, bromaniline, iodoaniline, toluidine and xylidine isomers and shows advantageous separation capability over the com. polysiloxane stationary phase. This work presents a promising future of calixarene-based ionic liquid as a new type of stationary phase in GC separations This study involved multiple reactions and reactants, such as Methyl heptanoate (cas: 106-73-0Application In Synthesis of Methyl heptanoate).
