1,5-Dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazolo[4,3-b]pyridine-6-carboxylic acid ethyl ester is a complex organic compound with the molecular formula C18H18N2O3. It is a derivative of pyrazolo[4,3-b]pyridine, a heterocyclic compound with a pyrazole and pyridine ring fused together. The molecule features two methyl groups at the 1st and 5th positions, a phenyl group at the 2nd position, and a carboxylic acid group at the 6th position, which is esterified with an ethyl group. 1,5-Dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazolo[4,3-b]pyridine-6-carboxylic acid ethyl ester is characterized by its unique structure and potential applications in medicinal chemistry, particularly as a precursor for the synthesis of biologically active molecules. Its chemical properties and reactivity can be influenced by the presence of the ester group, which can undergo hydrolysis to form the corresponding carboxylic acid. The compound's stability, solubility, and potential interactions with biological targets make it an interesting candidate for further investigation in drug development and chemical research.
The CAS Registry Mumber 1096-88-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,9 and 6 respectively; the second part has 2 digits, 8 and 8 respectively. Calculate Digit Verification of CAS Registry Number 1096-88: (6*1)+(5*0)+(4*9)+(3*6)+(2*8)+(1*8)=84 84 % 10 = 4 So 1096-88-4 is a valid CAS Registry Number.
