摘要：

Chromotropic acid is known to provide a specific and sensitive reagent for the detection of nitrate ion. The reaction is most sensitive in about 70% sulfuric acid. NMR studies indicated that the product was a mononitro derivative of chromo-tropic acid. The UV spectrum indicated that the product was a quinone compound. It is proposed that the structure of the product is a mononitro-quinone derivative of chromotropic acid in a polymerized sulfonyl form. © 1969.
