33282-15-4, Name is 5-(4-Hydroxyphenyl)isoxazole-3-carboxylic acid, belongs to isoxazole compound, is a common compound. HPLC of Formula: C10H7NO4In an article, once mentioned the new application about 33282-15-4.
The low-temperature n.m.r. spectra at the 13C frequency (25.16 MHz) showed the non-equivalence of the ortho-and meta-carbons in a number of substituted N-alkylanilines.Line-shape analysis, or measurement at the coalescence temperature, yielded the free energy of activation for the rotational process about the C-N bond.The deltaG* values were found to be linearly related to the Hammett constants for a variety of para-substitued derivatives.The barriers were found also to decrease with an increase in the size of the alkyl substituents bonded to the nitrogen atom.
