| titleOfInvention | 1-(2-pyridyl-azo)-4-cyclo-pentylresorcinol as reagent for photometric identification of bivalent cobalt |
| abstract | The invention relates to substituted pyridine, in particular 1- (2-pyridyl-azo) -4-cyclopentylresorcinol (PR), which can be used as a reagent for the photometric determination of dvc covalent cobalt. To reveal useful properties among compounds of the indicated class, a new PR was obtained. Synthesis of HGR is carried out by the synthesis of pyridine by the Chichibin reaction, followed by the diazotization of 2-aminopyridine and the combination of the 2-aminopyridine diazotate and cyclopentylresorcinol in ethanol. The PR test in Co (+2) photometry shows a better sensitivity than the well-known 1- (2-pyridyl-azo) -2-naphthol, while lowering the lower limit of detectable cobalt concentrations to 1 µg. 4 tab.
