What is 2-Ethoxybenzoic acid?

Part I: Introduction

     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 2-Ethoxybenzoic acid which has developed particularly rapidly in recent years. Do you know about 2-Ethoxybenzoic acid?

The official answer: 2-Ethoxybenzoic acid is an organic chemical substance used as a pharmaceutical intermediate and also in organic synthesis, molecular formula: C9H10O3

How is 2-Ethoxybenzoic acid synthesized?

Part 2: In-depth development

Methyl o-ethoxybenzoate is synthesized from methyl salicylate ([119-36-8]) and ethyl iodide, which is then hydrolyzed and acidified to produce methyl o-ethoxybenzoate. Sodium metal, methyl salicylate, and ethyl iodide were added to anhydrous methanol and refluxed for 10 h. The methanol and ethyl iodide was recovered and poured into cold water, and the oil was separated. The oil was washed with water and 5% sodium hydroxide solution to pH=7, extracted with ether, dried with anhydrous sodium carbonate and refluxed with ether, then distilled under reduced pressure to obtain methyl o-ethoxybenzoate. It was added to 5% sodium hydroxide solution and refluxed for 2-3h, cooled, and the unreacted ester was extracted with ether. The extracted aqueous solution is acidified with hydrochloric acid and the oil layer is washed with water. Then add 5% sodium hydroxide to dissolve, filter, and acidify again with hydrochloric acid to remove the oil layer and freeze to crystallize the crude product. The aqueous layer after acidification can be extracted with ether, which can also be used to obtain part of the crude product. The crude product is distilled under reduced pressure to obtain the finished product of o-ethoxy benzoic acid. Used in pharmaceutical intermediates, organic synthesis

Keep the receptacle sealed, store it in a cool, dry place, and ensure that the workroom is well ventilated or exhausted. It should be stored separately from oxidizers, acids, and edible chemicals and should not be mixed. The storage area should be equipped with spill response equipment and suitable containment materials.

WHY THEY SAY TO US

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.
