Chemistry is traditionally divided into organic and inorganic chemistry. HPLC of Formula: C5H6N2O3, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 1123-49-5
We report a mild, fast, highly efficient and eco-friendly protocol for the green synthesis of pyrrolo[2,3-d]isoxazoles and a new series of novel benzyl bis-pyrrolo[2,3-d]isoxazoles from nitro styrylisoxazoles in SnCl 2-ionic liquid by reductive cyclization. These reactions were performed at ambient temperature which resulted in good yields in short reaction time, without requiring any organic solvent and catalyst.
If you are interested in 1123-49-5, you can contact me at any time and look forward to more communication. HPLC of Formula: C5H6N2O3
