Main Application Areas

Pharmaceutical Industry

Synthetic drug intermediates: For example, used in the preparation of Erythromycin Ethylsuccinate (macrolide antibiotics) and succinate antihypertensive drugs (such as Captopril intermediates).

Synthetic antipyretic and analgesic drugs: Derivatives generated through reaction with amines can serve as precursors for anti-inflammatory and analgesic drugs.

Polymer Materials Field

Synthetic polyester resins: Polyesters produced by polycondensation with diols (such as ethylene glycol and propylene glycol) can be used to prepare coatings, adhesives, and plastics, possessing good chemical resistance and mechanical properties.

Synthetic polyimides: Polyimide resins generated by reaction with diamine compounds are used in high-temperature resistant materials (such as insulating materials in the aerospace field).

Preparation of ion exchange resins: By introducing functional groups, ion exchange resins with adsorption properties are synthesized for water treatment or substance separation.

Fine Chemicals

Preparation of plasticizers: Such as dibutyl succinate and dioctyl succinate, used in polyvinyl chloride (PVC) plastics to improve their flexibility.

Synthetic surfactants: Their derivatives (such as sulfosuccinates) have excellent emulsifying and foaming properties and are used in detergents, cosmetics, etc.

As an acylating agent: Used in organic synthesis to introduce the succinyl group (-CO-CH₂-CH₂-CO-) to modify the structure and properties of organic compounds.

Agriculture and Food Industry

Synthetic plant growth regulators: Their derivatives can promote plant growth and increase yields.

As food additive intermediates: Used in the preparation of certain acidulants or preservatives (must comply with food safety standards).
