Methylene blue trihydrate(CAS: 7220-79-3)

Methylene blue trihydrate is a chemical compound with the formula C16H18ClN3S·3H2O. It is a deep blue crystalline solid that is commonly used as a dye and a photosensitizer. The compound is known for its ability to absorb light and generate reactive oxygen species, making it valuable in various scientific and industrial applications.

Methylene blue trihydrate is widely used in pharmaceuticals as an antidote for methemoglobinemia, in medical diagnostics for urine tests, and in research for its photodynamic properties. It also finds applications in textile dyeing, water treatment, and as a fungicide in agricultural settings.

Methylene blue trihydrate is generally considered safe when used as directed. However, it can be toxic if ingested in large amounts or inhaled. Proper handling, including the use of protective gear, is recommended. Safety standards ensure its controlled use in medical and industrial contexts to minimize risks.

Methylene blue trihydrate should be stored in a cool, dry, and light-protected place. It is typically kept in airtight containers to prevent moisture absorption. The recommended storage temperature is between 15°C to 25°C, and it should be stored away from strong oxidizing agents to maintain stability and efficacy.
