Methyl2-methylbutyrate (cas: 868-57-5) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. 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.

Stability of low density lipoprotein particles affect the formation of off-flavor in thermal egg yolk was written by Ren, Liuyang;Ma, Jie;Xu, Weili;Lv, Ying;Tong, Qigen. And the article was included in Food Research International in 2022.Safety of Methyl2-methylbutyrate This article mentions the following:

This study aimed to investigate the role of stability of low d. lipoprotein (LDL) spherical particles as well as oxidation of lipids and proteins on formation of off-odor in heated egg yolk (EY). Off-odor attributes and volatile components of EY with different thermal temperature (25°C-90°C) were investigated by sensory evaluation, gas chromatog.-mass spectrometry (GC-MS) and GC-ion mobility spectrometry (IMS). The off-flavor and volatile compounds increased significantly when EY were heated at 60°C-65°C. Destruction of LDL particle structure was presented by confocal laser scanning microscopy with thermal treatment at 60°C. A pos. correlation (r = 0.899, p < 0.05) was shown between oil exudation and off-odor of heated EY. Moreover, oxidation of lipids and proteins, protein aggregation, and changes of protein secondary structure (increased β-sheets and decreased α-helixes) in LDL particles were all found when heating temperature rose to 65°C. It was speculated that unstability of LDL particles resulted in the leakage of lipids; then oxidative products of lipids took part in the formation of off-odor volatiles in heated EY. In the experiment, the researchers used many compounds, for example, Methyl2-methylbutyrate (cas: 868-57-5Safety of Methyl2-methylbutyrate).
