(NTP, 1992)|Methylene Blue is a synthetic basic dye. Methylene blue stains to negatively charged cell components like nucleic acids; when administered in the lymphatic bed of a tumor during oncologic surgery, methylene blue may stain lymph nodes draining from the tumor, thereby aiding in the visual localization of tumor sentinel lymph nodes. When administered intravenously in low doses, this agent may convert methemoglobin to hemoglobin.|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 is used as a bacteriologic stain and as an indicator. It inhibits GUANYLATE CYCLASE, and has been used to treat cyanide poisoning and to lower levels of METHEMOGLOBIN.Basic Info-

Reactivity Profile:METHYLENE BLUE TRIHYDRATE is incompatible with strong oxidizing agents, caustics, alkali metal iodides and reducing agents. Also incompatible with dichromates. It forms double salts with many inorganic salts. Is bleached reversibly by (zinc + hydrochloric acid) or sodium hydrosulfite. In aqueous solution, this chemical is decolorized by zinc dust and dilute sulfuric acid, but the color is restored upon exposure to air and more rapidly upon addition of ammonium hydroxide.
