What is Succinic anhydride?

  • 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 Succinic anhydride which has developed particularly rapidly in recent years. Do you know about Succinic anhydride?
  • The official answer: Succinic anhydride is an organic compound with the molecular formula C4H4O3, which is used in large quantities as a food additive and as a flavoring agent for soy sauce, sake, beverages, etc. It can be used as a modifier for alkyd resins and unsaturated polyester resins, which can improve their adhesion and water resistance. It is also used as the raw material of medicine; a cross-linking agent of ion exchange resin, etc.Colorless needle-like or granular crystal, soluble in ethanol, trichloromethane, and carbon tetrachloride, slightly soluble in water and aether. It can be hydrolyzed to succinic acid in hot water.

What’s the application of Succinic anhydride?

  • It is used in organic synthesis and is the raw material for alkyd resins, adhesive resins and anthraquinone dyes for paints, and in medicine for the production of vitamin A and sulfonamides, etc.
  • Used in the manufacture of pharmaceuticals, plasticizers, adhesives, etc.
  • Succinic anhydride is the intermediate of fungicide bacteriocin and plant growth regulator butylhydrazine.
  • It is a raw material for paints, pharmaceuticals, synthetic resins and dyes. Paint made from it has flex resistance and water resistance, and it is used in medicine to produce vitamin A and sulfa drugs. Pesticides are used to produce fungicides, insecticides and plant growth regulators. Butanedioic anhydride and its derivatives are used as catalysts for olefin polymerization, cross-linking agents for ester polymer condensates, light stabilizers for polymers, ultraviolet absorbers, etc. They are also used as oil field auxiliaries. Butanic anhydride can also be used to produce plasticizers. It is also used in defense system.
  • Succinic anhydride is an important organic synthesis intermediate. In the pharmaceutical industry, it is used for the synthesis of chloramphenicolsodiumsuccinata, hydroxyprogesterone sodium succinate, hydrocortisone sodium succinate, etc.
  • It is a raw material for paints, pharmaceuticals, synthetic resins and dyes. It is used in pharmaceuticals to produce vitamin A and sulfonamides, etc. Pesticides can be used to produce fungicides, insecticides and plant growth regulators. Succinic anhydride can also be used to produce plasticizers. It is also used in defense system.
  • Used as analytical reagent, also used in the pharmaceutical industry and the synthesis of ester resins.

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.
