Methyl green

Description:
Methyl green is a synthetic dye and a member of the triarylmethane family, primarily used as a biological stain and pH indicator. It appears as a green powder and is soluble in water, exhibiting a vibrant green color in its protonated form. Methyl green has a pH range of approximately 0 to 1, where it transitions from green to yellow as the pH increases. This property makes it useful in various applications, including histology and microbiology, for staining nucleic acids and differentiating between cellular components. The compound is also utilized in the field of analytical chemistry for detecting and quantifying certain substances. Methyl green is generally considered safe for laboratory use, but like many chemical substances, it should be handled with care, following appropriate safety protocols to avoid inhalation or skin contact. Its CAS number, 7114-03-6, uniquely identifies it in chemical databases, facilitating its recognition and study in scientific literature.
