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 feature bent C–O–C linkages. In dimethyl ether, the bond angle is 111° and C–O distances are 141 pm. The barrier to rotation about the C–O bonds is low. The bonding of oxygen in ethers, alcohols, and water is similar. In the language of valence bond theory, the hybridization at oxygen is sp3.Recommanded Product: 1877-75-4

Bismuth(III)-mandelate/DMSO: a new oxidizing system for the catalyzed carbon-carbon cleavage of epoxides was written by Zevaco, Thomas;Dunach, Elisabet;Postel, Michele. And the article was included in Tetrahedron Letters in 1993.Recommanded Product: 1877-75-4 This article mentions the following:

Bi(III)-mandelate was found to be an effective catalyst for the oxidative C-C bond cleavage of epoxides and their transformation into carboxylic acids in anhydrous DMSO medium. Thus, 1,7-octadiene 1,2-oxide (I) was treated with the title catalyst in Me2SO at 90° for 24 h to give 50% CH2:CH(CH2)4CO2H. Similar treatment of styrene oxide at 75° for 22 h gave 60% PhCO2H. In the experiment, the researchers used many compounds, for example, 2-(4-Methoxyphenoxy)acetic acid (cas: 1877-75-4Recommanded Product: 1877-75-4).
