Uses
Used in Inks, Paints, and Plastics Industry:
Pigment Yellow 5 is used as a coloring agent in the production of inks, paints, and plastics. It provides a vibrant yellow hue to these products, enhancing their visual appeal and making them more attractive to consumers.
Used in Textile Industry:
In the textile industry, Pigment Yellow 5 is used as a dye to impart a bright yellow color to fabrics. Its synthetic nature ensures consistent color quality and durability, making it a popular choice for manufacturers.
Used in Food Industry:
Pigment Yellow 5 is used as a food coloring agent to add a yellow tint to candies, sodas, chips, and other food products. Its ability to provide a consistent and appealing color makes it a preferred choice in the food industry.
Used in Pharmaceutical Industry:
In the pharmaceutical industry, Pigment Yellow 5 is used to color certain drugs, making them more visually appealing and potentially improving patient compliance with medication regimens.
However, it is important to note that there have been concerns about the safety of Pigment Yellow 5, with some research suggesting potential links to hyperactivity in children and allergic reactions. As a result, its use is regulated in most countries, with strict guidelines on the maximum allowable concentrations to ensure consumer safety.
Check Digit Verification of cas no
The CAS Registry Mumber 4106-67-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,0 and 6 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4106-67:
(6*4)+(5*1)+(4*0)+(3*6)+(2*6)+(1*7)=66
66 % 10 = 6
So 4106-67-6 is a valid CAS Registry Number.

Paragraph 0162; 0163; 0164, (2019/01/07)
The invention relates to a method used for synthesizing an azo compound using solid particle one kettle method. The method comprises following steps: solid particles are introduced into a reaction container, an inorganic acid, an aromatic primary amine, sodium nitrite, water, and a coupling component are added, mechanism stirring is carried out, when the reaction is monitored to be finished, filtering and rinsing are carried out, and the obtained filter cake is a finished product; or the solid particles are introduced into the reaction container, the inorganic acid, the aromatic primary amine,sodium nitrite, and water are added, mechanical stirring is carried out, after complete conversion of the aromatic primary amine, the coupling component is added, mechanical stirring is carried out,when the reaction is monitored to be finished, filtering and rinsing are carried out, and the obtained filter cake is a finished product. The solid particles are preferably selected from polytetrafluoroethylene particles, haw seeds, or stainless steel sand. The solid particles are added into the reaction system to promote reaction, no pre-heating or alkali adding dissolving of diazo components orthe coupling component is needed; most reaction is finished in 1h; reaction time is short; product quality is high; and reaction filtrate and excess inorganic acid can be recycled for a plurality of times.
