Cui, Wen-hui et al. published their research in Hecheng Huaxue in 2006 | CAS: 1877-75-4

2-(4-Methoxyphenoxy)acetic acid (cas: 1877-75-4) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. Ethers can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. The ability to form hydrogen bonds with other compounds makes ethers particularly good solvents for a wide variety of organic compounds and a surprisingly large number of inorganic compounds.Electric Literature of C9H10O4

Synthesis of 2-[(aryloxy)methyl]benzimidazole derivatives was written by Cui, Wen-hui;Zhang, You-min;Wei, Tai-bao. And the article was included in Hecheng Huaxue in 2006.Electric Literature of C9H10O4 This article mentions the following:

Twelve derivatives of 2-[(aryloxy)methyl]-1H-benzimidazole were synthesized using HCl as a catalyst and the structures were identified by 1H NMR, IR and elemental anal. Six of the compounds are reported for the first time. In the experiment, the researchers used many compounds, for example, 2-(4-Methoxyphenoxy)acetic acid (cas: 1877-75-4Electric Literature of C9H10O4).
