Sodium sulfide nonahydrate has been used as a standard for the quantification of volatile sulfur compounds in cheese samples by gas chromatography. It reacts with 4-(2′-hydroxyaryl)-2-(N,N-dialkylamino)-1,3-dithiolium perchlorates in ethanol at room temperature and boiling ethanol to form 1,3-dithiole-2-thiones and 2′-hydroxyacetophenones, respectively.
