Dimethyl succinate (Dimethyl Succinate, DMS) is an important organic chemical raw material, which is widely used in medicine, pesticide, plastic, spice and other fields. In the field of chemical production raw materials, there are many upstream and downstream related products of dimethyl succinate, some of which are described in detail below.

upstream associated products:

1. Succinic acid: dimethyl succinate is made from the esterification of succinic acid and methanol, so succinic acid is the main upstream raw material of dimethyl succinate.
2. Methanol: Methanol is another important raw material in the production of dimethyl succinate, which is esterified with succinic acid to produce dimethyl succinate.

downstream related products:

1. 1,4-Butanediol (BDO): dimethyl succinate can generate 1,4-butanediol through hydrogenation reduction reaction, which is an important chemical raw material, can be used to produce tetrahydrofuran, γ-butyrolactone, polybutylene terephthalate (PBT) and other products.
2. Succinimide: Succinimide can be obtained by the reaction of dimethyl succinate with ammonia, which is an important pharmaceutical intermediate and can be used to produce anti-tuberculosis drugs, antifungal drugs, etc.
3. Pesticides: dimethyl succinate can be used to produce some pesticides, such as butachlor, imidacloprid and so on.
4. Plastic plasticizer: dimethyl succinate can be used as a plastic plasticizer to improve the processing performance and flexibility of plastics.

In short, dimethyl succinate has a wide range of upstream and downstream related products in the field of chemical production raw materials, which is of great significance to promote the development of the chemical industry.
