Haessner, Rainer’s team published research in Magnetic Resonance in Chemistry in 28 | CAS: 14580-22-4

Magnetic Resonance in Chemistry published new progress about 14580-22-4. 14580-22-4 belongs to pyrazoles-derivatives, auxiliary class Organic Pigment, name is 1-(2-Chlorophenyl)-3-methyl-5-pyrazolone, and the molecular formula is C10H9ClN2O, COA of Formula: C10H9ClN2O.

Haessner, Rainer published the artcileCarbon-13 NMR data for chlorine- or nitro-substituted azomethine dyes, COA of Formula: C10H9ClN2O, the publication is Magnetic Resonance in Chemistry (1990), 28(9), 817-19, database is CAplus.

The 13C NMR of 1-aryl-substituted 3-methyl-2-pyrazolin-5-ones and their azomethine dyes have been recorded and assigned. Ortho substituents (Cl and NO2) on the Ph ring in the 1-position of the pyrazoline moiety show a small influence on the chem. shift of the azomethine bond carbon atom, C-4.
