Santavy, Frantisek et al. published their research in Collection of Czechoslovak Chemical Communications in 1970 | CAS: 4741-62-2

5-Methoxyisobenzofuran-1(3H)-one (cas: 4741-62-2) belongs to benzofurans derivatives. Benzofuran is a core structural unit found in many naturally occurring compounds with multidirectional biological activities. They are also prone to polymerisation in the presence of concentrated mineral acids and Lewis acids.Name: 5-Methoxyisobenzofuran-1(3H)-one

Ultraviolet spectra, methoxy, and methylenedioxy groups of some aromatic compounds and alkaloids. II. The effect of methoxy and methylenedioxy groups on the ultraviolet spectra of aromatic compounds with a conjugated carbonyl chromophore was written by Santavy, Frantisek;Hruban, Ladislav;Simanek, Vaclav;Walterova, D.. And the article was included in Collection of Czechoslovak Chemical Communications in 1970.Name: 5-Methoxyisobenzofuran-1(3H)-one This article mentions the following:

Characteristic changes in the location and intensity of absorption bands in the uv region are given and discussed with regard to the nature and position of the electron donating O-containing substituents in numerous derivatives of benzene, indanones, protoochotensimine compounds, phthalic acids, protopine and oxyprotopine alkaloids. In the experiment, the researchers used many compounds, for example, 5-Methoxyisobenzofuran-1(3H)-one (cas: 4741-62-2Name: 5-Methoxyisobenzofuran-1(3H)-one).
