The meso-13C chem. shifts were revealed to serve as a powerful probe to determine the coordination structure (five vs. six coordinate) and electron configuration (high spin vs. low spin) of ferric porphyrin complexes. In the experiment, the researchers used many compounds, for example, 3,5-Dimethylpyridine 1-oxide (cas: 3718-65-8HPLC of Formula: 3718-65-8).
3,5-Dimethylpyridine 1-oxide (cas: 3718-65-8) belongs to pyridine derivatives. In contrast to benzene, Pyridine’s electron density is not evenly distributed over the ring, reflecting the negative inductive effect of the nitrogen atom. Pyridine groups exist in countless molecules, and their applications include catalysis, drug design, molecular recognition, and natural product synthesis.HPLC of Formula: 3718-65-8
