It is a yellow-orange powder that is insoluble in water but soluble in organic solvents. The compound is known for its strong coloration and is often used in a variety of industrial applications, including coloring plastics, textiles, and various coatings. Additionally, it has been studied for its potential antimicrobial and anticancer properties. However, it is important to note that CI Solvent Yellow 56 may pose health risks if not handled properly, and precautions should be taken when working with this chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 6407-74-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,0 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6407-74:
(6*6)+(5*4)+(4*0)+(3*7)+(2*7)+(1*4)=95
95 % 10 = 5
So 6407-74-5 is a valid CAS Registry Number.

A quantitative one-pot synthesis method for industrial azo pigments with recyclable wastewater

Most industrial azo pigments are synthesized by diazotization in one pot and then coupling in another. This two-pot process has been transformed into a one-pot method by adding granular PTFE (polytetrafluoroethylene) to a mechanically agitated aqueous mixture of NaNO2, HCl, a diazo component and a coupling component. This method avoids the step of using a base or a surfactant to dissolve the coupling component. The reactions were fast and quantitative. The granular PTFE, wastewater and excess HCl were then reused 11 times without deteriorating the reaction rate and product purity. Altogether, 22 industrial pigments and 3 azo compounds were synthesized and the reaction can produce up to 22.7 g of product in the laboratory. Some reactions require less than 2 equiv. of HCl and a mechanism explaining this is proposed. In addition, an o-nitro group effect is advanced to explain the differences in coupling reaction rates for o-, m- and p-nitroaniline.
