abstract: alpha-Amino acids are converted into fluorescent derivatives of dihydrolutidine. Primary and secondary alkylamines are determined by converting them into sulphonamides by means of 1-dimethylamino-naphthalene-5-sulphonyl chloride. A fluorescent adduct is given by the reaction of tertiary alkylamines with alpha,gamma-anhydroaconitic acid in acetic anhydride, and a fluorescence is obtained by condensing indoles with formaldehyde in the presence of an oxidizing agent. Furfural, obtained by the dehydration of pentoses, is determined by converting it into a 1,8-dioxodecahydroacridine derivative. 2,6-Di-t-butyl-p-cresol allows the fluorimetry of Delta(4) and Delta(1,4)-3,11-diketosteroids. The fluorescence of Pyronine G decreases under the action of Delta(5(10))-3-keto-19-norsteroids.
