197775-45-4 Usage
General Description
5-Pyridin-4-yl-4H-pyrazole-3-carboxylic Acid is a chemical compound with the molecular formula C9H6N4O2. As suggested by its name, it contains Pyridin, Pyrazole, and Carboxylic Acid functional groups. This chemical is classified under the heterocyclic compound category, a significant class of organic chemicals that contain a cyclic structure with atoms of at least two different elements. It is likely to appear as a white or off-white solid and may be used in pharmaceuticals, among other applications. Concerning safety, specific precautions, handling, and hazardous properties will still follow standard chemical protocols. Its exact properties and uses would likely be determined through further research and experimentation.
Check Digit Verification of cas no
The CAS Registry Mumber 197775-45-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,7,7 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 197775-45:
(8*1)+(7*9)+(6*7)+(5*7)+(4*7)+(3*5)+(2*4)+(1*5)=204
204 % 10 = 4
So 197775-45-4 is a valid CAS Registry Number.

A novel pyridine-pyrazole based selective “turn-off” fluorescent chemosensor for Fe(III) ions
Madhu,Sivakumar
, p. 341 - 348 (2019)
A novel pyridine-pyrazole based “turn-off” fluorescent chemosensor namely, 5-N-(pyridine-2-yl)-3-(pyridine-4-yl)-1H-pyrazole-5-carboxamide (PPPC) was designed, synthesized and well characterized by NMR, ESI-MS and FT-IR spectroscopic techniques. UV–vis absorption and fluorescence spectroscopic studies show that PPPC exhibits high selectivity and sensitivity towards Fe3+ ion in DMSO/H2O solution (9:1, v/v) over other metal ions. The binding constant (K) of PPPC with Fe3+ was calculated to be 5.1 × 10?2 M and 6.1 × 10?2 M from Benesi-Hildebrand plot using UV–vis and fluorescence spectrophotometer respectively. The detection limit of PPPC for Fe3+ was further determined as 57 nM and 88 nM by UV–vis and fluorescence titrations. Moreover, the binding mechanism of Fe3+ with PPPC was confirmed by DFT study.
