Benouatas, Assia; Laroum, Rima; Hamdouni, Noudjoud; Zemamouche, Wissame; Debache, Abdelmadjid; Boudjada, Ali published an article in 2021. The article was titled 《Structural study and Hirshfeld surface analysis of (Z)-4-(2-methoxybenzylidene)-3-phenylisoxazol-5(4H)-one》, and you may find the article in Acta Crystallographica, Section E: Crystallographic Communications.Quality Control of 2-Methoxybenzaldehyde The information in the text is summarized as follows:
The title compound, C17H13NO3, adopts a Z configuration about the C=C bond. The isoxazole and methoxybenzylidene rings are almost coplanar with a dihedral angle of 9.63 (7)° between them. In contrast, the Ph substituent is twisted significantly out of the plane of the oxazole ring, with the two rings inclined to each other by 46.22 (4)°. The crystal structure features C-H···O, C-H···N and C-H···π hydrogen bonds and π-π contacts. An anal. of the Hirshfeld surfaces points to the importance of H···H, H···C/C···H and H···O/O···H contacts. The included surface areas of the title compound were compared to those of the isomeric structure (Z)-4-(4-methoxybenzylidene)-3-phenylisoxazol-5(4H)-one [Zhang et al. (2015). CrystEngComm, 17, 7316-7322]. The experimental part of the paper was very detailed, including the reaction process of 2-Methoxybenzaldehyde(cas: 135-02-4Quality Control of 2-Methoxybenzaldehyde)
2-Methoxybenzaldehyde(cas: 135-02-4) is found in cassia oil, cinnamon bark, and cinnamon bark oil. It is a clear colorless liquid with a strong aroma. It has been used to examine the acaricidal activity of Periploca sepium oil and its active component against Tyrophagus putrescentiae.Quality Control of 2-Methoxybenzaldehyde
