3-(2,4-Dimethoxyphenyl)acrylic acid (cas: 6972-61-8) belongs to ethers. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive, and as a result they are useful as solvents for fats, oils, waxes, perfumes, resins, dyes, gums, and hydrocarbons. Vapours of certain ethers are used as insecticides, miticides, and fumigants for soil. At room temperature, ethers are pleasant-smelling colourless liquids.

Identification and analysis of free and O-glycoside-bound volatile components in wild Rosa roxburghii juice was written by Zhou, Zhi;Wang, Xing-ping;Luo, Zu-you;Fan, Gang;Tian, Cheng;Tang, Qiao-yu;Pan, Si-yi. And the article was included in Shipin Kexue (Beijing, China) in 2012.Reference of 6972-61-8 This article mentions the following:

Wild Rosa roxburghii juice from Xuan En, E’ Zhou was extracted by headspace solid-phase microextraction (HS-SPME) to obtain free volatile components, and adsorbed with Amberlite XAD-2 column and hydrolyzed with β-glucosidase to release O-glycoside-bound volatile components. Both volatile compounds were analyzed by gas chromatog.-mass spectroscopy (GC-MS). The results indicated that there was a significant difference observed in the composition and contents of free volatile components and O-glycoside-bound volatile components. In total 38 free volatile compounds and 38 O-glycoside-bound volatile compounds were identified. The major free volatile compounds were (+)-limonene, leaf alc., Et butyrate, hexanol, styrene, Et isovalerate, 2,4-di-tert-butylphenol, γ-terpinene, β-myrcene, β-ocimene, 3-hexenyl butyrate, linalool, octanoic acid, Et caprylate and (-)-dipentene. Meanwhile, the major O-glycoside-bound volatile compounds were 4-hydroxycinnamic acid, 4’5′-dimethyl-2′-hydroxyacetophenone, octanoic acid, cinnamic acid, 2,4-di-tert-butylphenol, 3,4-dimethoxycinnamic acid, benzyl alc., hexanoic acid, 3,4,5-trimethoxyphenol, leaf alc. and 4-hydroxy-3-methoxycinnamic acid. In addition, 33 compounds were found only in the O-glycoside-bound volatile components, which were benzyl alc., phenylethyl alc., neroli, cinnamic acid, vanillic acid, 3-hydroxybutyric acid Et ester, eugenol, and so on. In the experiment, the researchers used many compounds, for example, 3-(2,4-Dimethoxyphenyl)acrylic acid (cas: 6972-61-8Reference of 6972-61-8).
