Methylene Blue trihydrate (Basic blue 9) is a compound consisting of dark green crystals or crystalline powder, having a bronze-like luster. Solutions in water or alcohol have a deep blue color. Methylene Blue trihydrate is used as a bacteriologic stain and as an indicator. It inhibits soluble guanylyl cyclase and has been used to treat cyanide poisoning and to lower levels of methemoglobin. It also inhibits tau filament formation (IC50: 1.9μM).

Toluidine Blue (Blutene chloride), a phenothiazine, is used as a biological stain, a hemostatic, and a dye for silk and wool. Blutene chloride is also used as a diagnostic aid for gastric neoplasms and oral, and used in the identification of the parathyroid gland in thyroid surgery.

Bromothymol Blue, a pH indicator, appears yellow in acidic conditions and blue in alkaline environments.
