Methyl2-methylbutyrate (cas: 868-57-5) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Formula: C6H12O2

Synthesis and pyrolysis of two novel pyrrole ester flavor precursors was written by Fan, Wenpeng;Chu, Wenjuan;Tian, Haiying;Zhang, Zhan;Feng, Yingjie;Gao, Ziting;Cheng, Biao;Ji, Xiaoming;Lai, Miao. And the article was included in Journal of Heterocyclic Chemistry in 2022.Formula: C6H12O2 This article mentions the following:

In order to develop the high-temperature-released pyrrole aroma, two novel flavor precursors of 1H-pyrrole-3-carboxylates I (R = n-Bu, Ph) were synthesized using glucosamine hydrochloride and Me acetoacetate as raw materials through cyclization, oxidation, alkylation, reduction, and esterification. The target compounds were characterized by NMR (1H NMR, 13C NMR), IR spectroscopy (IR) and high-resolution mass spectrometry (HRMS). Thermogravimetry (TG), differential scanning calorimeter (DSC) and the pyrolysis-gas chromatog./mass spectrometry (Py-GC/MS) methods were used to analyze the heating-stability of the target compounds, and the pyrolysis mechanism was inferred. Py-GC/MS results indicated that some fragrance compounds were formed during thermal degradation such as 2-methylbutyric acid, 2-methylbutyrate, alkylpyrroles, and benzoic acid, which were important aroma components or flavor additives. This provided a theor. reference for the application of pyrrole ester in cigarette and heat-processed food flavoring. In the experiment, the researchers used many compounds, for example, Methyl2-methylbutyrate (cas: 868-57-5Formula: C6H12O2).
