Basic Violet 4

Description:

Basic Violet 4, also known as Crystal Violet or Gentian Violet, is a synthetic dye belonging to the triphenylmethane class. It is characterized by its deep purple color and is soluble in water and alcohol, making it useful in various applications. The chemical structure features three phenyl rings connected by a central carbon atom, contributing to its vibrant hue. Basic Violet 4 is commonly used in biological staining, particularly in microbiology for staining bacteria and fungi, as well as in histology for tissue samples. Additionally, it has applications in the textile industry for dyeing fabrics and in some cases, as an antiseptic in medical settings. The compound exhibits basic properties, which allows it to interact with acidic substances, forming salts. However, it is important to note that Basic Violet 4 can be toxic and may cause skin irritation or allergic reactions in some individuals. As with many synthetic dyes, environmental considerations regarding its disposal and potential ecological impact are also important.

Ethyl violet

CAS: 2390-59-2

Ethyl violet is a cationic surfactant. It is used as a dye in analytical chemistry to measure the adsorption of glycol ethers on metal oxide surfaces, and it has also been used as a model system for studying the adsorption of detergents on metal oxide surfaces. The adsorption mechanism of ethyl violet on metal oxide surfaces involves an electrostatic attraction between the positively charged ethyl violet molecule and the negatively charged surface. Ethyl violet has been shown to be carcinogenic in mice, although its carcinogenic potential in humans remains unclear. Ethyl violet can be synthesized from glycol ethers and hydrochloric acid by titration calorimetry.
