What is O,O-Dimethyl phosphoramidothioate(methyl methacrylate)?

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 O,O-Dimethyl phosphoramidothioate(methyl methacrylate) which has developed particularly rapidly in recent years. Do you know about O,O-Dimethyl phosphoramidothioate(methyl methacrylate)?


The official answer:Spermine is a polyamine containing two amino and two imino groups and is a biologically active, low molecular weight aliphatic nitrogenous base produced during biological metabolism. Spermine is not abundant in living organisms but is a regulatory substance necessary for the synthesis of nucleic acids and proteins in microorganisms, animals, and humans. Most of the biological functions of spermine are based on electrostatic reactions with DNA, RNA, proteins, and electrically charged membrane components. It is a colorless, transparent Chemicalbook or light white liquid in appearance and is produced in living organisms from putrescine (butane diamine) and S-adenosylmethionine catalyzed by a variety of enzymes. It is mainly used to produce pesticide intermediates such as methamidophos and acetamiprid. It is found in bacteria and most animal cells, along with spermidine, and is an important substance in promoting cell proliferation. Under acidic conditions, it exhibits polycationic polyamine properties and binds to DNA in viruses and bacteria. It gives DNA molecules greater stability and flexibility and is one of the essential components of cell culture fluids.

What’s the application of O,O-Dimethyl phosphoramidothioate(methyl methacrylate)?

O, O-dimethyl phosphoramidothioate is referred to as spermidine or spermicide and is an intermediate in the synthesis of methamidophos.

It is mainly used as an intermediate for methamidophos and acetylmethamidophos.

The preparation method is based on the amination of methyl chloride as raw material. A certain amount of methyl chloride and the appropriate amount of solvent into the porcelain-lined reaction kettle cooled to about 0 ℃ under stirring, and then a certain amount of ammonia slowly drop into, control the reaction temperature at about 20 ℃, about 1.5h plus Chemicalbook finished, insulation 0.5h after sampling and analysis, to detect no methyl chloride chromatographic peak as the endpoint. The material is pumped into the extraction kettle and left to stratify, the oil layer is the crude amine product, and then by lifting the membrane system desolvation is obtained after the fine amide, content 90% ~ 93%, the moisture content is less than 0.2%.

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.
