Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.21905-86-2, you can also check out more blogs about21905-86-2

New discoveries in chemical research and development in 2021.21905-86-2,Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. Which mentioned a new discovery about 21905-86-2, Name is Cinnoline-4-carboxylic acid, molecular formula is C9H6N2O2.

10764] To a stirred solution of N1-cyclopropyl-5-fluo- robenzene-1,2-diamine mt-i (500 mg, 3.01 mmol) in DMF (5 mE) under an inert atmosphere was added cinnoline-4- carboxylic acid (524 mg, 3.01 mmol), HATU (1.71 g, 4.51 mmol) and diisopropylethylamine (1 mE, 6.02 mmol) at 00 C. The reaction mixture was stirred at room temperature for 16 h. Afier consumption of starting material (by TEC), the reaction mixture was diluted with water (20 mE) and extracted with EtOAc (2×20 mE). The combined organic extracts were washed with water (20 mE), dried over anhydrous Na2SO4 and concentrated under reduced pressure to obtain N-(2-(cyclopropylamino)-4-fluorophenyl) cinnoline4-carboxamide (500 mg, crude) as brown solid used in the next step without further purification.10765] EC-MS: m/z 322.9 [M+H] at 2.71 RT (38.30% purity).
