Description
ETHYL VIOLET is an organic chloride salt that is the monochloride salt of ethyl violet cation. It is a green to olive-green crystalline powder with a black violet appearance. It is used for inclusion in mixed dye solutions of the iron resorcin fuchsin type for demonstrating elastic fibres.
Uses
Used in Biomedical Applications:
ETHYL VIOLET is used as a staining agent for pancreatic tissue and elastin in the detection of gram-negative bacteria. It aids in the visualization and identification of these tissues and bacteria under microscopic examination.
Used in Analytical Chemistry:
ETHYL VIOLET is used as a reagent for the extractive-spectrophotometric determination of anionic surfactants. It helps in the quantitative analysis of these surfactants in various samples.
Used in Metal Analysis:
ETHYL VIOLET is used in the extraction and spectrophotometric determination of copper. It enables the detection and quantification of copper ions in different matrices.
Used in Protein Analysis:
Along with the anionic dye zincon, ETHYL VIOLET is used as a counterion dye of proteins in SDS-polyacrylamide gel electrophoresis. It assists in the separation and identification of proteins based on their molecular weight.

Check Digit Verification of cas no
The CAS Registry Mumber 2390-59-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,9 and 0 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2390-59:
(6*2)+(5*3)+(4*9)+(3*0)+(2*5)+(1*9)=82
82 % 10 = 2
So 2390-59-2 is a valid CAS Registry Number.

Method for preparing triarylmethane compounds and application thereof
-
Paragraph 0034-0036, (2019/11/13)
The invention discloses a method for preparing a triarylmethane dye. 4,4'-N,N-disubstituted aminodiphenylmethane (bass) and aromatic amines or substituted aromatic amines, phenols or substituted phenols are dissolved in a solvent, metal complexes and tetrachlorobenzoquinone are used as catalysts and oxygen is used as oxidant, the mixture reacts for 5-8 hours at acid conditions and a certain temperature, so that the product triarylmethane dye is obtained in one step, and the commercialized product is obtained through further treatment, so as to meet the application requirement in different fields. The method is simple and safe, and has high yield and less three-wastes.
