Overview
Congo corinth is an organic sodium salt resulting from the formal condensation of Congo corinth (acid form) with two equivalents of sodium hydroxide. A histological dye used to stain frozen sections for rapid diagnosis and to demonstrate amuloid. It has a role as a fluorochrome and a histological dye. It contains a Congo corinth(2-).
