Orcinol reaction with rna
Orcinol is an organic compound with the formula CH3C6H3(OH)2. It occurs in many species of lichens including Roccella tinctoria and Lecanora. Orcinol has been detected in the "toxic glue" of the ant species Camponotus saundersi. It is a colorless solid. It is related to resorcinol, 1,3-C6H4(OH)2.
