Name: 5-(hydroxymethyl)-2,4-dimethylpyridin-3-ol hydrochloride. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: 5-(hydroxymethyl)-2,4-dimethylpyridin-3-ol hydrochloride, is researched, Molecular C8H12ClNO2, CAS is 148-51-6, about Gas electron diffraction and quantum chemical study of the structure of a 2-nitrobenzenesulfonyl chloride molecule.

A combined gas electron diffraction and quantum chem. (B3LYP/6-311+G**, B3LYP/cc-pVTZ, B3LYP/cc-pVTZ, midix (Cl), and MP2/cc-pVTZ) study of the structure of a 2-NO2-C6H4-SO2Cl mol. is performed. It is found exptl. that at a temperature of 345(5) K the gas phase contains two conformers of the C 1 symmetry. Conformer I with a nearly perpendicular arrangement of the S-Cl bond with respect to the benzene ring plane (the C(NO2)-C-S-Cl torsion angle is 84(3)°) is contained predominantly (69(12)%). In conformer II, the S-Cl bond is located near the benzene ring plane (the C(NO2)-C-S-Cl angle is 172(3)°). The following exptl. internuclear distances (Å) are obtained for conformer I: rh1(C-H) = 1.064(15), rh1(C-C)av = 1.397(3), rh1(C-S) = 1.761(6), rh1(S-O)av = 1.426(4), rh1(S-Cl) = 2.043(5), rh1(N-O)av = 1.222(4), rh1(C-N) = 1.485(16). In both conformers, the NO2 group is turned by more than 30° relative to the benzene ring plane.
Although many compounds look similar to this compound(148-51-6)Name: 5-(hydroxymethyl)-2,4-dimethylpyridin-3-ol hydrochloride, numerous studies have shown that this compound(SMILES:OC1=C(C)C(CO)=CN=C1C.[H]Cl), has unique advantages.
