What is Methylene Blue trihydrate?
Methylene Blue trihydrate is a chemical compound that is a hydrated form of methylene blue, a synthetic dye and heterocyclic aromatic chemical compound. The trihydrate form means that each molecule of methylene blue is associated with three molecules of water.
Chemical Information:
Chemical Formula: C16H18ClN3S·3H2O
Molecular Weight: 373.90 g/mol (including the three water molecules)
CAS Number: 7220-79-3 (for the trihydrate form)
Appearance: Dark green crystalline powder or solid that gives a blue solution when dissolved in water.
Key Properties:
Solubility: Soluble in water and ethanol, producing a blue solution.
Color: Produces a deep blue color when dissolved, which is characteristic of methylene blue.
Stability: Generally stable under standard conditions, but should be protected from light as it can degrade when exposed to prolonged light.
Applications:
Biological Staining:
Microscopy: Used as a stain in various biological and histological procedures to highlight cell structures, particularly in tissues and bacteria. It is commonly used in Gram staining as a counterstain and in other staining protocols to visualize cell nuclei and other components.
Vital Staining: Used to stain living cells or tissues, helping to differentiate between live and dead cells in certain applications.
Medical Uses:
Antidote: Used as an antidote for methemoglobinemia, a condition where hemoglobin is unable to release oxygen effectively to body tissues. Methylene blue helps convert methemoglobin back to hemoglobin.
Diagnostic Agent: Sometimes used in procedures like the Schilling test, which assesses vitamin B12 absorption.
Antimicrobial Activity: Has some antimicrobial properties and has been used in various treatments, including urinary tract infections and as a topical antiseptic.
Chemical Redox Indicator:
Redox Reactions: Acts as a redox indicator in chemical experiments. It is blue in its oxidized form and becomes colorless when reduced, making it useful for demonstrating redox processes.
Aquaculture and Fishkeeping:
Treatment for Fish Diseases: Used in aquaculture and fishkeeping to treat fungal infections, parasites, and certain bacterial infections in fish.
Textile Industry:
Dye: Although less common today, methylene blue has been used historically as a dye in the textile industry.
Safety and Handling:
Toxicity: While generally safe at low concentrations, methylene blue can be toxic in higher doses, particularly if ingested or injected. It can cause side effects like nausea, vomiting, and in extreme cases, hemolytic anemia.
Handling Precautions: Should be handled with care, using appropriate personal protective equipment (PPE) such as gloves and safety glasses, especially in laboratory settings.
Storage:
Storage Conditions: Store in a cool, dry place away from light to prevent degradation. Keep in tightly closed containers to avoid moisture absorption and contamination.
Methylene Blue trihydrate is a versatile compound with applications ranging from biological staining to medical treatments, making it a valuable chemical in various fields of science and medicine.
