【Abstract】 Heterocyclic azo dyes are one group of the most important chromogenic reagents in spectrophotometric analysis. Up to now more than 500 reagents were synthesized. According to the literature materials the relationship between structures and analytical functions of heterocyclic azo reagents has been summarized and analyzed in this paper. Full text involves 122 references. We believe that the review will furnish fresh evidence for further research on new chromogenic reagents.更多还原
