General Description
1-HYDROXY-3-METHYL-5-PHENYL-1H-PYRAZOL-2-IUM-2-OLATE is a chemical compound with the molecular formula C11H10N2O2. It is a pyrazole derivative that contains a hydroxyl group and a methyl group attached to the pyrazole ring, as well as a phenyl group. The compound is a pyrazolium salt and is commonly used in organic synthesis and medicinal chemistry. It has potential pharmacological applications due to its unique structure and properties. However, further research is needed to fully understand the potential uses and effects of 1-HYDROXY-3-METHYL-5-PHENYL-1H-PYRAZOL-2-IUM-2-OLATE.
Check Digit Verification of cas no
The CAS Registry Mumber 136229-96-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,2,2 and 9 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 136229-96:
(8*1)+(7*3)+(6*6)+(5*2)+(4*2)+(3*9)+(2*9)+(1*6)=134
134 % 10 = 4
So 136229-96-4 is a valid CAS Registry Number.

Stereochemical Effects in the Nitrosation of Some α,β-Unsaturated Ketoximes. Formation of 1-Hydroxypyrazole 2-Oxides and 4-Oximino-4,5-dihydroisoxazoles

Several α,β-unsaturated ketoximes R1CH=CHC(=NOH)R2 were nitrosated using butyl nitrite in aqueous ethanol in the presence of copper(II) sulfate and pyridine.The product distribution varied depending on whether the oxime hydroxyl group was syn or anti with respect to the carbon-carbon double bond.The anti-oximes gave the copper complexes of 1-hydroxypyrazole 2-oxides in high yields.The isomeric syn-oximes gave lower yields of the pyrazole complexes along with 4-oximino-4,5-dihydroisoxazole derivatives.For the syn-oximes where R1 is phenyl and R2 is either methyl or ethyl, conversion of the oximes to the parent ketones was also observed.The results may be explained by processes involving N-nitrosonitrone intermediates.
