1. Chemical and Materials Fields

– As a plasticizer:

Primarily used in polyvinyl chloride (PVC) and similar plastics to improve material flexibility and processing performance. Compared to phthalate plasticizers, citrate esters are generally considered a more environmentally friendly and safer option.

– As a polymer additive:

It plays a role in various polymerization reactions, such as as a foaming agent for methyl methacrylate polymers, a stabilizer for acrylamide, and an initiator for polyamide adhesives.

– Used in adhesive synthesis:

It is one of the main raw materials for the production of hot melt adhesives.

2. Fine Chemical Intermediates
As a stable organic synthesis intermediate, it is used in the production of various downstream chemicals.

– Main raw material for the synthesis of citric acid:

Citrine acid has a wide range of applications, including as a color photosensitive additive, oilfield adsorbent, electroplating additive, and water-soluble dye.

– Pharmaceutical and pesticide synthesis:

It is often used as a key chemical intermediate in the synthesis processes of pharmaceuticals and pesticides.

– Daily Chemical Additives:

Can be used as an additive in daily chemical products, such as in pharmaceutical coatings.

3. Biomedical and Materials Science (Emerging Applications)
Based on its biocompatibility and biodegradability, it shows potential in scientific research and high-value-added fields.

– Biomedical Materials:

Used to develop citrate-based biomaterials (CBBs). These materials possess good biocompatibility, biodegradability, and tunable mechanical properties, and are being studied for applications in tissue engineering, wound healing, and cardiovascular materials.

– Drug Delivery Systems:

Due to its ability to form stable emulsions and enhance drug solubility, it is being studied as a drug carrier for constructing controlled-release drug delivery systems.

– Antibacterial Research:

Studies show that it and its derivatives possess certain antibacterial properties, showing potential applications in combating foodborne pathogens.

4. Other Specific Uses

– Colored Flame Candle Main Fuel:

Due to its specific melting point and flammability, it is often used as the main fuel in manufacturing colored flame candles, enabling the candles to produce bright colored flames when burning.

– Industrial Additives:

In the petroleum industry, it can be used as a hydrophilic core component of a highly efficient demulsifier for separating water-in-oil emulsions at low temperatures. In the textile industry, it can undergo transesterification with cellulose for wrinkle-resistant finishing of cotton fabrics.
