Trimethyl citrate[2]
Overview
Trimethyl citrate is an ester derived from citric acid, widely recognized for its versatility in industrial and food applications. It is a clear, colorless to pale yellow liquid with a mild odor, often used as a plasticizer in polymers and as a food additive due to its non-toxic nature. As a biodegradable compound, trimethyl citrate is increasingly favored in environmentally sensitive applications. Its synthesis involves the esterification of citric acid with methanol, resulting in a product that combines the benefits of citric acid derivatives with enhanced solubility and stability.
Physical and Chemical Properties
Trimethyl citrate exhibits a molecular weight of 234.20 g/mol and a density of 1.19 g/cm³. It is soluble in water, ethanol, and most organic solvents, making it highly adaptable for various formulations. The compound has a melting point of approximately 15-18°C and decomposes around 280°C. Its key chemical properties include stability under normal conditions and compatibility with a wide range of materials. These characteristics make it suitable for applications requiring non-toxic, biodegradable, and efficient plasticizing agents.
Main Applications
Trimethyl citrate is primarily used as a plasticizer in the production of polymers, where it enhances flexibility and durability without compromising safety. It is also employed as a food additive, particularly in beverages and confectionery, to regulate acidity and improve flavor. In the pharmaceutical industry, it serves as an intermediate in drug formulations. Its non-toxic and biodegradable nature makes it a preferred choice for eco-friendly products, including adhesives, coatings, and personal care items.
Safety and Storage
Trimethyl citrate is generally regarded as safe (GRAS) for food applications, but standard laboratory precautions should be followed during handling. It is advisable to use protective gloves and eyewear to prevent skin and eye contact. Storage should be in a cool, dry, well-ventilated area, away from direct sunlight and oxidizing agents. Proper sealing of containers is essential to maintain product integrity and prevent contamination.
B2B Procurement Guide
When procuring trimethyl citrate, ensure the supplier provides detailed specifications, including purity levels and CAS number verification. Food-grade applications require additional certifications to comply with safety standards. Price ranges typically vary between $10-$30 per kg, depending on quantity and supplier. Bulk purchases may offer cost advantages, but always prioritize quality and regulatory compliance to avoid potential issues in end-use applications.
