Methyl violet 2B (Tetramethylparosanilinium chloride, 4,4'-[(4-Imino-2,5-cyclohexadien-1-yliden)methylen]bis(N,N-dimethylaniline)hydrochloride) is a violet triarylmethane dye from the group of cationic dyes and an essential component of C.I. Basic Violet 1 (trivial name methyl violet). Methyl violets are mixtures of tetramethyl (2B ...
Methyl violet is a mutagen and mitotic poison, therefore concerns exist regarding the ecological impact of the release of methyl violet into the environment. Methyl violet has been used in vast quantities for textile and paper dyeing, and 15% of such dyes produced worldwide are released to environment in wastewater. Numerous methods have been ...
The name gentian violet was originally used for a mixture of methyl pararosaniline dyes (methyl violet), but is now often considered a synonym for crystal violet. The name refers to its colour, being like that of the petals of certain gentian flowers; it is not made from gentians or violets .
The leaves were found to be useful as absorbent material for the removal of textile dyes, such as reactive orange 16, [26] Rhodamine B, [27] methylene blue, malachite green [28] and methyl violet 2b. [29] Similarly, the dried cone was also reported to be able to remove Rhodamine B, [30] and methyl violet 2b. [31]
Common side effects include headache, nausea, and vomiting. While use during pregnancy may harm the fetus, not using it in methemoglobinemia is likely more dangerous. [6] [2] Methylene blue was first prepared in 1876, by Heinrich Caro. [9] It is on the World Health Organization's List of Essential Medicines. [10]
Multiple additional studies in the United States, [11] Canada, [12] and Australia [13] similarly failed to find benefits of megavitamin therapy to treat schizophrenia. The adrenochrome theory of schizophrenia waned, despite some evidence that it may be psychotomimetic , as adrenochrome was not detectable in people with schizophrenia.
There are many uses of the leftover tarap peels, stem axis and seeds. The tarap peels were reported as useful material for the removal of colouring agents (such as crystal violet, [4] methyl violet 2B and methylene blue [5]) from dye wastewater. The tarap stem axis were reported to be used in the removal of Cd (II) and Cu(II). [6]
Methemoglobinemia, or methaemoglobinaemia, is a condition of elevated methemoglobin in the blood. [2] Symptoms may include headache, dizziness, shortness of breath, nausea, poor muscle coordination, and blue-colored skin (cyanosis). [2]
