3-Hydroxy-5-methoxybenzaldehyde (cas: 57179-35-8) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. At room temperature, ethers are pleasant-smelling colourless liquids. 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.Reference of 57179-35-8

Study on chemical constituents of Ranunculus ternatus Thumb was written by Li, Haibin;Du, Shushan;Hou, Fengfei;Wang, Dacheng;Liu, Guifang;Yang, Hongwu. And the article was included in Shenyang Yaoke Daxue Xuebao in 1999.Reference of 57179-35-8 This article mentions the following:

Ten compounds were isolated from Ranunculus ternatus Thumb by chromatog. methods, and six of them were identified. The six compounds were identified as stigmasterol (I), hexadecanoic acid (II), eicosanoic acid (III), nonacosanol (IV), ternatolide A (V), and 5-hydroxy-3-methoxy-benzaldehyde (VI). In the experiment, the researchers used many compounds, for example, 3-Hydroxy-5-methoxybenzaldehyde (cas: 57179-35-8Reference of 57179-35-8).
