One of the major reasons is to use measurements of the macroscopic properties of a system, the rate of change in the concentration of reactants or products with time, to discover the sequence of events that occur at the molecular level. 875-66-1, introduce a new downstream synthesis route., 875-66-1875-66-1

a. [4-CHLOROCINNOLINE] (9b). A mixture of 4-hydroxycinnoline (2.0 g, 13.7 mmol), phosphorus oxychloride (1.94 mL, 20.5 mmol), and pyridine (0.33 mL, 4.1 mmol) in [CHLOROBENZENE] (50 mL) was refluxed for 1 hour. Then the mixture was cooled and the solvent evaporated under vacuum, water was added, and the mixture was neutralized with solid sodium bicarbonate and extracted with chloroform (3 x 100 mL), washed with water (3 x 100 mL), dried [(MGS04)] and evaporated under vacuum, giving 1.84 g, in 82 % yield; [MP] [76-77 C] (lit mp 78 [C)] [; IH] NMR [(CDC13)] [8] 7.91 (m, 2H), 8.20 (dd, 1H, [J=6.] 2, [J=2.] 1), 8.57 (dd, 1H, J=6. 6, J=1. 8), 9.34 (s, [1H)] ; [13C NMR (CDCL3) No. ] 123.0, 124.9, 130.2, 131.6, 132.3, 133.8, 134.9, 144.4.
