What is Sodium 4-amino-1-naphthalenesulfonate?

With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Sodium 4-amino-1-naphthalenesulfonate which has developed particularly rapidly in recent years. Do you know about Sodium 4-amino-1-naphthalenesulfonate?

 

The official answer: Sodium 1-naphthylamine-4-sulfonate (common name: sodium 4-amino-1-naphthalenesulfonate, abbreviated as sodium 1,4ate) is an important intermediate of azo pigments [1], which is widely used in the synthesis of direct and reactive dyes, and also sodium 1,4ate is one of the antidotes for nitrites and iodine poisoning. In recent years, it has been found that both the amino and sulfonic acid groups of sodium 1,4ate can be well-coordinated with power supply atoms, so sodium 1,4ate can be used as both a donor and an acceptor for hydrogen bonding, making sodium 1,4ate widely used in complexation with various metals (such as Fe, Zn, Cd, Ni, etc.) for the synthesis of toxic chemical leak surveillance devices, optical devices, gas absorption materials, and clinical medical research. 4 sodium acid is also used in thermal switches, optical switches and materials for information storage components, DNA structural probes, and DNA molecular optical switches. In the laboratory, sodium 1-naphthylamine-4-sulfonate is often supplied as sodium 1-naphthylamine-4-sulfonate tetrahydrate.

What’s the application of Sodium 4-amino-1-naphthalenesulfonate?

Sodium 1-naphthylamine-4-sulfonate industrial product is off-white crystal, often contains two crystal water or four crystal water, fading to rose color in the air, very soluble in water, soluble in 95% ethanol. 1-naphthylamine-4-sulfonate is one of the important intermediates of azo pigments, widely used in the synthesis of direct dyes, reactive dyes, and also one of the antidotes for nitrite type and iodine poisoning. In recent years, it has been found that both the amino and sulfonic acid groups of sodium 1-naphthylamine-4-sulfonate can be well-coordinated with power supply atoms, so sodium 1-naphthylamine-4-sulfonate can be used as both the donor and the acceptor of hydrogen bonds, which makes sodium 1-naphthylamine-4-sulfonate widely used in complexation with various metals (such as Fe, Zn, Cd, Ni, etc.) for toxic chemical leak surveillance equipment, optical devices, gas absorption Sodium 1-naphthylamine-4-sulfonate is also used in the fields of thermal switches, optical switches and information storage components, DNA structural probes, DNA molecular optical switches, etc.

Peter has been my partner for many years, we met at the Shanghai CPHI Fair in 2014, for the first time I didn't have much interest in Peter's products because our company had a stable supplier. Although we didn't work together, Peter would often send me important news and interesting trend information about the industry, so we became good friends, even though I didn't place any orders with him during this time, even if it was a sample order. In September 2016, our original supplier was unable to provide us with the quality and delivery guarantees we needed, so I first thought of Peter and his company. Until now, we have maintained a very good personal friendship in addition to a steady business relationship.

In all my years of sourcing from China, I first time to found that working with Sincere Chemical was so good, they helped me with all the production and delivery as well as a lot of technical expertise, which saved me a lot of time. When I first approached Peter for a quotation for Optical Brightener, he made me a detailed quotation with not only prices but also foreign trade details, company profile, company strengths, R&D capabilities, production capacity, packaging methods, raw material control, environmental protection, and much more. This information was a very important reference for me in making purchasing decisions. Sincere Chemical is a trustworthy supplier and I believe our business will grow from strength to strength!

Hi, I'm Kim, I'm Peter's partner and although I don't like him very much (because he never gives me more money for my prices, hahaha) I'm still willing to write him customer feedback. As an international buyer, I have to deal with a lot of things every day and my inbox is often full of development letters. It's a lot of junk and meaningless pleasantries, which I don't like that much, but Peter's emails always give me a better understanding of the product and the industry. I am also very pleased with his work ethic, and I am very happy with his work every time I work with him, not only in providing quotations but also in facilitating all the details of my work so that I can concentrate more on other things, so he is the best supplier for me. Although his prices are not the lowest among all suppliers, his products give me the greatest peace of mind.
