N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4) belongs to amides. The solubilities of amides and esters are roughly comparable. Typically amides are less soluble than comparable amines and carboxylic acids since these compounds can both donate and accept hydrogen bonds. Tertiary amides, with the important exception of N,N-dimethylformamide, exhibit low solubility in water. Amides can be freed from solvent or water by drying below their melting points. These purifications can also be used for sulfonamides and acid hydrazides.Reference of 10543-57-4

Study on microetching performance of hydrogen peroxide/sulfuric acid system was written by Yang, Yan;Li, De-liang. And the article was included in Advanced Materials Research (Durnten-Zurich, Switzerland) in 2011.Reference of 10543-57-4 This article mentions the following:

In order to get the optimum technol. conditions of the hydrogen peroxide/sulfuric acid system, the static corrosion method was used to study the related parameters including compositions of the microetching system and the operation temperature The results of the experiment show that the microetching performance of the hydrogen peroxide/sulfuric acid system was excellent under optimum conditions of maintaining temperature at 30∼35°C, copper concentration about 25 g/L, hydrogen peroxide 30∼40 g/L and sulfuric acid content 70∼90 g/L. The process of microetching is stable and controllable. In the experiment, the researchers used many compounds, for example, N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4Reference of 10543-57-4).
