Product Description
Tripropyl Citrate, CAS 1587-21-9, is the tri-n-propyl ester of citric acid. Its molecular formula is C15H26O7 and its molecular weight is 318.36 g/mol. The substance carries the European Community number 216-450-8 and the IUPAC name tripropyl 2-hydroxypropane-1,2,3-tricarboxylate. The molecule retains the central hydroxyl group of citric acid together with three ester functions, a structure that places it within the citrate ester group of carboxylic acid esters.
The product is a liquid at 20 C with a density of 1.08 g/cm3 and a boiling point of 198 C at 13 mmHg. The relatively high boiling point under reduced pressure points to low volatility, a property that matters when an ester is used in formulations that are processed or stored at elevated temperature. Dideu Group supplies this material with an assay of not less than 97.0 percent by gas chromatography, and each batch is released with a certificate of analysis stating the tested results.
Tripropyl Citrate is commonly handled in laboratory and pilot quantities, and Dideu Group therefore offers it across a graduated range from 1 g up to 1 kg, which allows buyers to start with a small evaluation quantity and scale up without changing supplier. The minimum order quantity is 1 g, orders are normally ready for dispatch within 7 working days, and payment is accepted by T/T and L/C. Shipments are arranged by courier or by air and reach customers in global markets.
Potential Applications
Public technical literature on this specific ester is limited. It is classified as a plasticizer, and the directions below are drawn from that classification, from the citrate ester family in general and from the molecule structure. They are stated as potential uses and should be verified by the buyer through its own formulation trials.
- Plastics and Polymers: May be used as a plasticizer for polar polymers, including poly(vinyl chloride) and biodegradable polyesters such as polylactic acid, where citrate esters are a well-known additive family.
- Polymer Research and Development: May serve as a model compound in chain-length studies of citrate ester plasticizers, for example when comparing methyl, ethyl, propyl and butyl esters in the same polymer matrix.
- Paints and Coatings: May be evaluated as a low-volatility ester additive in film-forming systems, where such esters can influence flexibility and film coalescence.
- Printing Inks: May be used as a low-volatility ester solvent or co-solvent in ink formulations that require reduced evaporation during printing.
- Adhesives and Sealants: May be added to adhesive resins as a plasticizing component to adjust tack, flexibility and open time.
- Lubricants and Greases: Citrate esters appear in published friction modifier compositions, so this ester may be screened as a component of lubricant additive packages.
- Pharmaceutical Development: May be investigated as a plasticizer for polymeric film coatings on tablets, capsules and granules, an application in which citrate esters are widely studied.
- Analytical and Laboratory Use: Frequently supplied as a research reagent for organic synthesis, ester chemistry studies and analytical method development.
Note: except for the plasticizer classification, the application directions listed above are indicative rather than confirmed uses for this specific ester. Buyers are advised to confirm suitability for their own end use before scale-up.
