Some examples of the diverse research done by chemistry experts include discovery of new medicines and vaccines, improving understanding of environmental issues, and development of new chemical products and materials.21905-86-2. Introduce a common compound, CAS is 21905-86-2, Name is Cinnoline-4-carboxylic acid, belongs to cinnolinecompound.

To a solution OF 4- [ (Z)- (4-BROMOPHENYL) (ethoxyimino) methyl]-1- (4-methyl-4- piperidinyl) piperidine (50 mg, 0.12 MMOL), cinnoline-4-carboxylic acid (25mg, 0.14 mmol), Et3N (0.06 mL, 0.43 MMOL) in DMF (3 mL, anhydrous) was added HATU (60mg, 0. 16MMOL) at room temperature. After 16 h the reaction mixture was poured into ice water, and the solid was collected by filtration. The solid was dissolved in CH2CI2, and dried over NA2SO4. Concentration in vacuo, and purification by preparative TLC (CH2CI2-MEOH, 9: 1) afforded the title compound as a light yellow powder. MS: 564 (M+).
