3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride (cas: 65-22-5) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.Formula: C8H10ClNO3

Structural divergence in binuclear Cu(II) pyridoxal Schiff base complexes probed by co-ligands: catecholase mimetic activity and sulphide ion sensing was written by Chakraborty, Moumita;Mondal, Antu;Chattopadhyay, Shyamal Kumar. And the article was included in New Journal of Chemistry in 2020.Formula: C8H10ClNO3 The following contents are mentioned in the article:

Three hydroxymethyl bridged Cu(II) complexes of a pyridoxal Schiff base ligand 4-((E)-(2-(pyridin-2-yl)ethylimino)methyl)-5-(hydroxymethyl)-2-methylpyridin-3-ol (LH) were synthesized and characterized on the basis of spectroscopic, electrochem. and structural properties. The x-ray crystal structures of the complexes reveal dual denticity of the ligand, bidenticity in the absence of a co-ligand as in complex 1, and tridenticity in the presence of a co-ligand such as SCN–/N(CN)2– as in complexes 2 and 3. The complexes, though binuclear in the solid state, exist as a monomeric unit in solution due to the exceptionally long axial Cu-Ohydroxymethyl (2.4-2.5 Å) bond. All three complexes show efficient catalytic activities towards the aerial oxidation of 3,5-di-tert-butylcatechol (DTBCH2) with kcat values of 5.38 x 104 h-1, 1.18 x 105 h-1 and 1.06 x 105 h-1 in methanol. Complexes 1 and 2 also act as a selective sulfide ion sensor with Kb values of 6.6 x 103 M-1 and 8.1 x 103 M-1, resp., while their resp. L.O.D. values are 3.4μM and 3.2μM. This study involved multiple reactions and reactants, such as 3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride (cas: 65-22-5Formula: C8H10ClNO3).
