Ethyl methyl cyanoacetate (EMCA) is an important organic chemical raw material, which is widely used in medicine, pesticide, dye and other fields. Its upstream and downstream related products are numerous, and several major upstream and downstream products are described in detail below.

1. Upstream product

(1) Cyanoacetic acid: Cyanoacetic acid is one of the important raw materials for the production of ethyl methyl cyanoacetate, which can be prepared by the reaction of glyoxylic acid and hydrocyanic acid.

(2) Methanol: Methanol is another raw material for the production of ethyl methyl cyanoacetate. It reacts with cyanoacetic acid to produce methyl cyanoacetate through esterification.

(3) Sulfuric acid: In the production process, sulfuric acid is used as a catalyst to promote the esterification reaction.

2. Downstream product

(1) Pesticide: Ethyl methyl cyanoacetate can be used to produce a variety of pesticides, such as pesticides, fungicides and herbicides. For example, ethyl methylcyanoacetate can be used as an intermediate in the synthesis of pyrethroid insecticides.

(2) Pharmaceutical intermediates: ethyl methyl cyanoacetate can be used to produce a variety of pharmaceutical intermediates, such as anti-tumor drugs, antibacterial drugs, etc. These pharmaceutical intermediates can be further synthesized to obtain drugs for clinical use.

(3) Dye: Ethyl methylcyanoacetate can be used as a dye intermediate to produce a variety of dyes, such as acid dyes, direct dyes, etc.

In short, as an important organic chemical raw material, ethyl methyl cyanoacetate has a wide range of upstream and downstream related products and involves many fields, which is of great significance to promote the development of related industries.
