Ethyl 3-oxo-3-(m-tolyl)propanoate (cas: 33166-79-9) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.HPLC of Formula: 33166-79-9

Organic dye photocatalyzed α-oxyamination through irradiation with visible light was written by Liu, Hongjun;Feng, Wei;Kee, Choon Wee;Zhao, Yujun;Leow, Dasheng;Pan, Yuanhang;Tan, Choon-Hong. And the article was included in Green Chemistry in 2010.HPLC of Formula: 33166-79-9 This article mentions the following:

Rose Bengal, an organic dye, was used as a visible light photocatalyst to study novel α-oxyamination reactions between 1,3-dicarbonyl compounds and a free radical (TEMPO). Compounds that are difficult to obtain such as quaternary fluorinated compounds were synthesized using this method. This visible light photocatalytic reaction can also be performed in H2O. In the experiment, the researchers used many compounds, for example, Ethyl 3-oxo-3-(m-tolyl)propanoate (cas: 33166-79-9HPLC of Formula: 33166-79-9).
