89522-29-2 Usage
Pyrazoloquinoline family
Heterocyclic compounds with a pyrazolo ring fused to a quinoline ring This describes the general class of compounds to which 1H-Pyrazolo[3,4-b]quinoline belongs, highlighting the key structural features of these compounds.
Methyl group at the 3-position
A specific structural feature of 1H-Pyrazolo[3,4-b]quinoline, 3-methyl-, in which a methyl group is attached to the 3-position of the pyrazoloquinoline structure.
Heterocyclic compounds
Compounds containing one or more rings with non-carbon atoms This further describes the general class of compounds to which 1H-Pyrazolo[3,4-b]quinoline belongs, emphasizing the presence of non-carbon atoms in the rings.
Check Digit Verification of cas no
The CAS Registry Mumber 89522-29-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,5,2 and 2 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 89522-29:
(7*8)+(6*9)+(5*5)+(4*2)+(3*2)+(2*2)+(1*9)=162
162 % 10 = 2
So 89522-29-2 is a valid CAS Registry Number.

Friedlaender Condensation of 1H-Pyrazolin-5-ones with o-Aminobenzaldehydes. Synthesis of 1H-Pyrazoloquinolines
Tomasik, Danuta,Tomasik, Piotr,Abramovitch, Rudolph A.
, p. 1539 - 1543 (2007/10/02)
All the possible 1- and 3-monomethyl, monophenyl, dimethyl, diphenyl, and methylphenyl-1H-pyrazolin-5-ones have been condensed with o-aminobenzaldehyde.In some cases (but not all) 1-H-pyrazoloquinolines (10) are formed together with a variety of other products.The balance between formation of hydrazone 11 and the ring-closed 10 is discussed, as is the formation of other products obtained in these condensations.
