54709-94-3,54709-94-3, 5-Methylpyridazin-3(2H)-one is a pyridazine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Step 13B: 6-Oxo-1,6-dihydropyridazine-4-carboxylic acid To a stirred solution of the subtitle compound of Step 13A (4.4 g, 40 mmol) in concentrated sulphuric acid (80 mL), potassium dichromate (18 g, 61 mmol) was added in small quantities at 50-60 C. as a finely ground powder. The starting material was added to the mixture within 20 min. Stirring was continued for a further 10 min at 60 C., the viscous green mixture was poured on crushed ice. The solids were filtered off and washed with cold water. After drying in vacuo the subtitle compound was isolated (4.5 g, 77%). 1H NMR (400 MHz, (CD3)2SO): delta 7.22 (s, 3H), 8.13 (s,1H), 13.38 (s, broad, 1H).
The synthetic route of 54709-94-3 has been constantly updated, and we look forward to future research findings.
