General Description
5-Cyano-1-methyl-1H-pyrazole-4-carboxylic acid ethyl ester, also known as CTK2F9969, is a chemical compound characterized by its aromatic stucture and includes a cyanide, an ester and a carboxyl group. This chemical generally appears as a clear, colorless to light yellow liquid. It is utilized in the scientific and research field, particularly in organic synthesis. There is very limited available data regarding its environmental effects or potential hazards to human health, hence specific caution and protective measures should be taken while handling this chemical repeatedly or over a prolonged period of time. It does not have a wide range of commercial applications, rather its primary use is prevalent in specialized scientific settings. It is recommended that this chemical be stored in a cool, dry, well-ventilated area away from incompatible substances.
Check Digit Verification of cas no
The CAS Registry Mumber 33090-55-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,0,9 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 33090-55:
(7*3)+(6*3)+(5*0)+(4*9)+(3*0)+(2*5)+(1*5)=90
90 % 10 = 0
So 33090-55-0 is a valid CAS Registry Number.

Carbon-13 NMR Chemical Shifts of 1-Alkyl-3(5)-cyano-1H-pyrazole-4-carboxylic Acid Esters
Babbitt, George E.,Lynch, Michael P.,Beck, James R.
, p. 90 - 92 (2007/10/02)
A compilation of 13C NMR chemical shifts for 13 pairs of 3- and 5-cyano-substituted pyrazole regioisomers is reported.All of the ring carbon and cyano carbon 13C chemical shifts show a regular, predictable correlation with the particular isomer, whether 3-cyano or 5-cyano.These shifts occured in very narrow ranges, precluding any confusion of assignment within the group of compounds studied.X-ray crystallographic analysis was performed on one of the samples.
