125-20-2, Thymolphthalein is a benzofuran compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
preparation method as follow: thymolphthalein (4.3 g, 10 mmol), TBAHS (3. 4 g, 10 mmol), 2-acetamido-3,4,6 -tri-O-acetyl -2-deoxy- A -D-glucopyranoside (3.65g, 10 mmol) dissolved in dichloromethane and cooled down to 10 degrees. After adding 30 ml of 1N potassium carbonate aqueous solution, the mixture was stirred at room temperature for 3 hours, and the mixture was separated and dried over anhydrous sodium sulfate. The organic phase is concentrated to dry column to obtain thymolphthalein-N-acetyl-3,4,6-O-triacetyl-beta-D-glucapyranoside (Yield 4.5 g, yield 61.2%).
As the paragraph descriping shows that 125-20-2 is playing an increasingly important role.
