The acidity constants of 4-(2-thiazolylazo)-resorcinol (TAR) were determined by the principal component-wavelet neural network (WNN). Biprotic acid mass balance equations, the distribution functions and the corresponding spectral profiles which were generated by a Gaussian model, have been considered to simulate

A simple and rapid colorimetric assay for non-esterified fatty acids (NEFA) was developed employing extraction of samples with 0.1 mol/l glycine (pH 2.7) and methoxyethanol : butyl ether, and formation of a copper-fatty acid soap detected with 4-(2-thiazolylazo)-resorcinol. The method
