2390-60-5 Usage
Description
Basic Blue 7 is a bright brown powder that exhibits colorful red-blue light. It is slightly soluble in cold water, soluble in hot water to produce a blue color, and easily soluble in ethanol to also produce a blue color. When it comes into contact with strong sulfuric acid, it turns light yellow, and when diluted, it turns red for yellow. In nitric acid, it appears olive green. When the dye solution is mixed with sodium hydroxide, it turns red brown.
Uses
Used in Textile Industry:
Basic Blue 7 is used as a dye for silk, wool, and cotton cloth tannins mordant dyeing. It is suitable for various dyeing processes due to its colorfastness properties.
Used in Manufacturing Industry:
Basic Blue 7 is used in the manufacture of oil, carbon, ball pen wax paper, bamboo, and wood light color. Its versatility allows it to be applied in various products.
Used in Color Pigment and Solvent Dye Deposit Production:
Basic Blue 7 is also used in the production of color pigments and solvent dye deposits, contributing to the creation of a wide range of colored products.

Check Digit Verification of cas no
The CAS Registry Mumber 2390-60-5 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, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2390-60:
(6*2)+(5*3)+(4*9)+(3*0)+(2*6)+(1*0)=75
75 % 10 = 5
So 2390-60-5 is a valid CAS Registry Number.

Method for preparing triarylmethane compounds and application thereof
-
Paragraph 0037-0039, (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.
Carbenium ion-carbinol equilibration for basic triarylmethane dyes: Relative reactivities of dyes in aq. solutions
Gupta, Susanta K. Sen,Arvind, Udai
, p. 998 - 1000 (2007/10/02)
Equilibria and kinetics of carbenium ion-to-carbinol base reactions for a set of selected basic triarylmethane dyes in aq. buffer solutions of low ionic strength have been measured spectrophotometrically.Relative reactivities of the dyes towards nucleophilic attack by hydroxide ion, on the basis of both equilibrium constant and forward rate constant of the reaction, have been found to follow the same order: malachite green (MG)> brillant green (BG)>> Victoria pure blue BO(VB)> methyl violet (MV) = crystal violet (CV)> ethyl vioet (EV).A fairly good correlation between elec trophilicities of the dyes and ?R+ parameters of their 4-alkylamino substituents has been obtained
