About Methylene Blue trihydrate

It is a reddish brown, glossy columnar crystal or crystalline powder. Odorless, no change in air exposure, soluble in water and alcohol. Methylene blue is mild and safe to use, and it also helps to improve the respiratory function of fish.

Main Uses:
1) methylene blue can be used for dyeing;
2) Superior product methylene blue can be used for sterilization and disinfection;
3) Industrial grade methylene blue is used for dyeing cotton, acrylic fiber, hemp, silk and paper, and is also used for coloring bamboo and wood and for making ink (red ink) and color lake;
4) Analysis of pure methylene blue used as REDOX indicator, adsorption indicator and biological stain in chemical reagents, such as the determination of tin, boron and other metals, mixed indicator for serum protein test, shed cell test staining solution, basic methylene blue staining solution.
5) Analysis of pure methylene blue used for the determination of tin. Reductive titrant used to precipitate perchlorate and rhenate. Determination molybdenum by catalytic spectrophotometry.
6) Detoxification drugs can be used for nitrite, sulfonamide, cyanide poisoning antidote.
7) Methylene blue for the development of new materials.
8) Bacterial stain.

Versatile Laboratory Applications

Methylene Blue trihydrate serves a vital role in scientific research, particularly for biological staining, redox analysis, and educational demonstrations. Its ability to act as an indicator or dye makes it a valuable resource in microbiology, pharmaceutical studies, and aquaculture processes.

Handling and Storage Recommendations
