4,5-Dihydro-1-(4-methylphenyl)-3-phenyl-1H-pyrazole is a chemical compound belonging to the pyrazole class, characterized by a five-membered heterocyclic ring containing one nitrogen atom and four carbon atoms. This specific compound features a 4-methylphenyl group attached to the nitrogen atom at position 1 and a phenyl group at position 3. The compound is a dihydro derivative, meaning it contains two hydrogen atoms added across a double bond, which in this case is likely between the carbon atoms at positions 4 and 5 of the pyrazole ring. This chemical structure may have potential applications in various fields, such as pharmaceuticals or materials science, due to its unique properties and reactivity.

959-08-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 959-08-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,5 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 959-08:
(5*9)+(4*5)+(3*9)+(2*0)+(1*8)=100
100 % 10 = 0
So 959-08-0 is a valid CAS Registry Number.

Utility of Ketonic Mannich Bases in Synthesis of Some New Functionalized 2-Pyrazolines

Afsah, Elsayed M.,Keshk, Eman M.,Abdel-Rahman, Abdel-Rahman H.,Jomah, Najla F.

, p. 326 - 334 (2017/12/26)

The styryl ketonic Mannich base 2 has been used as a precursor in the synthesis of 2-pyrazolines having a basic side chain at C-3 and a phenolic Mannich base at C-5. Treatment of the bis(styryl ketonic bases) 6a and 8a with phenylhydrazine affords the bis(3-functionalized 2-pyrazolines) 7 and 9. The transamination between the styryl keto base 10 and 4-aminoantipyrine leads to 12, which reacts with piperazine to give 13. N-Nitrosation of the sec-Mannich bases 15a–d followed by reductive cyclization affords 2-pyrazolines 17a–d. The keto base 14b has been used for the synthesis of 2-pyrazolines having a phenolic Mannich base at C-3 and its reaction with 3,5-dimethyl-1H-pyrazole affords 23. The alkylation of 3-methyl-1-phenyl-2-pyrazolin-5-one with the bis(Mannich base) 25 was investigated.
