Bial's reagent consists of 0.4 g orcinol, 200 ml of concentrated hydrochloric acid and 0.5 ml of a 10% solution of ferric chloride.

Orcinol is an organic compound with the formula CH 3 C 6 H 3 (OH) 2. It occurs in many species of lichens [3] 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-C 6 H 4 (OH) 2.
