12222-97-8 - Introduction
Disperse blue 102, also known as methylene blue, is an organic dye. Here is the relevant information about disperse blue 102:
Nature:
-Appearance: Usually dark blue to purple crystalline powder.
-Solubility: Soluble in organic solvents such as water, ethanol and chloroform.
-Chemical structure: The chemical formula of Disperse Blue 102 is C37H35N3Na2O9S3.
-Stability: relatively stable to light and heat.
Use:
-Dye application: Due to its bright color and good hydrophilicity, Disperse Blue is 102 commonly used in the dye industry to dye textiles (such as polyester fibers) and plastic products.
-Biomedical applications: Disperse blue 102 is also used as a biological dye for observing cells and tissues under the microscope.
Preparation Method:
-Disperse blue 102 can be obtained by synthesis. A common synthetic method is to obtain methylene blue sulfite by reacting ammonium sulfite with methylene blue aldehyde. Then, a dispersion blue 102 is obtained by a substitution reaction of a sodium compound or other reactions.
Safety Information:
-This compound may be potentially toxic to humans, so avoid direct contact with skin, eyes and mouth.
-Appropriate protective measures, such as chemical gloves, goggles and protective clothing, must be taken during handling and storage.
-When handling disperse blue 102, you need to do it in a well-ventilated laboratory environment to avoid inhaling its powder or gas.
-When discarded, it should be disposed of in accordance with local chemical waste disposal regulations.
