Application of 575-03-1, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 575-03-1, name is 7-Hydroxy-4-(trifluoromethyl)coumarin. This compound has unique chemical properties. The synthetic route is as follows.
General procedure: To a magnetically-stirred solution of 7-hydroxycoumarin derivatives (2 mmol), aromatic aldehydes (2 mmol) and NEt3 (2 mmol) in THF (8 mL) a mixture of dialkyl acetylenedicarboxylate (2 mmol) in THF (2 mL) was added in 15 min. The reaction mixture was then allowed to stand at room temperature for 0.5-10 h. After completion of the reaction as indicated by thin-layer chromatography (TLC) (n-hexane/EtOAc, 1:1), the solvent was removed under reduced pressure. The residue was purified by column chromatography on silica gel (Merck, 230-400 mesh) using a mixture of n-hexane/EtOAc (1:1) as eluent to afford the pure product as a light yellow powder.
According to the analysis of related databases, 575-03-1, the application of this compound in the production field has become more and more popular.
