2-(4-Methoxyphenoxy)acetic acid (cas: 1877-75-4) belongs to ethers. The oxygen atom in ethers are more electronegative than carbon, thus the hydrogens which are alpha to the ethers are more acidic than the simple hydrocarbons. 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 1877-75-4

Studies on mixed trialkyltin derivatives. VII. Studies of [(phenyldimethylsilyl)methyl]dicyclohexyltin carboxylates was written by Xie, Qing-lan;Sha, Yin-lin;Yang, Zhi-qiang. And the article was included in Chemical Research in Chinese Universities in 1995.Reference of 1877-75-4 This article mentions the following:

Seventeen derivatives of mixed trialkyltin carboxylates (PhMe2SiCH2)Cy2SnO2CR were synthesized from ((PhMe2SiCH2)Cy2Sn)2O and RCO2H. The results of IR, NMR (1H, 13C, 119Sn) and MS showed that this kind of compounds is four-coordinated and that there are two good linear relations between the δ 119Sn and Hammett constants of para-substituent of the corresponding aryloxyacetates and arylcarboxylates. These compounds have a good acaricidal activity in the preliminary bioassay tests. In the experiment, the researchers used many compounds, for example, 2-(4-Methoxyphenoxy)acetic acid (cas: 1877-75-4Reference of 1877-75-4).
