Methylene Blue Trihydrate, scientifically identified by CAS number 7220-79-3, is a compound of significant interest across multiple industries due to its unique chemical and physical properties. As a reputable manufacturer and supplier, understanding this profile is key to leveraging its full potential.

In terms of its physical characteristics, Methylene Blue Trihydrate presents as a dark green crystalline powder. It often exhibits a subtle bronze sheen in its solid state. A defining feature is its behavior in solution: when dissolved in water, it imparts a deep, intense blue color. This solubility in water is a critical property for many of its applications, particularly in dyeing and staining. While soluble in water, it is sparingly soluble in ethanol and generally insoluble in non-polar solvents.

The chemical structure of Methylene Blue Trihydrate contributes to its utility. It is a thiazin dye and a cationic compound, which dictates its interaction with various substrates. Its molecular formula is C16H24ClN3O3S, with a molecular weight of approximately 373.90 g/mol. The 'trihydrate' designation indicates the presence of three water molecules within its crystalline structure, influencing its stability and handling properties.

The high purity of Methylene Blue Trihydrate, typically 99% minimum from reliable manufacturers, is crucial for consistent performance. This purity ensures that the dye's color intensity, solubility, and reactivity are predictable, which is vital for industrial processes and scientific accuracy.

The primary applications of Methylene Blue Trihydrate are diverse. In the textile industry, it is widely used for dyeing natural fibers like cotton, linen, silk, and hemp, known for its vibrant blue hues. It also finds extensive use in the manufacturing of inks and color lakes, contributing to the production of printing inks and stationery. For the scientific community, its role as a biological stain in microbiology and histology is indispensable for visualizing cells and tissues under a microscope. Furthermore, it's utilized in aquaculture for water treatment and as a redox indicator in various chemical and biological experiments.
