Description

Nonanoic Anhydride is a versatile organic acid anhydride derived from pelargonic acid, serving as a key acylating and esterifying agent in fine chemical synthesis. Its value lies in its ability to efficiently introduce the nonanoyl group, a medium-chain fatty acid moiety, into target molecules, modifying their properties for specific industrial applications. This compound is essential for manufacturers and R&D laboratories in the pharmaceutical, agrochemical, polymer, and fragrance industries seeking reliable, high-purity intermediates.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, where the nonanoic acid moiety can influence lipophilicity and bioavailability.
• Agrochemical Synthesis: Acts as a building block for producing herbicides, fungicides, and plant growth regulators that require specific fatty acid chains for efficacy.
• Polymer Modification: Employed as a monomer or modifier in the production of polyesters, polyamides, and alkyd resins to alter flexibility, hydrophobicity, and chemical resistance.
• Flavor and Fragrance Ingredient: Serves as a precursor for esters that contribute to fruity, waxy, or creamy notes in perfumery and food flavorings.
• Lubricant and Plasticizer Additive: Used to synthesize esters that function as synthetic lubricants, metalworking fluids, or specialty plasticizers.
• Surface Treatment Agent: Applied in the modification of surface properties for textiles, papers, or coatings to impart water repellency or specific functional groups.
• Chemical Research & Development: A valuable reagent in organic synthesis laboratories for acylation reactions and the study of reaction mechanisms.

Quality Control

Our Nonanoic Anhydride is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, identity, and consistency. A Certificate of Analysis (COA) detailing results for assay, impurities, and physical properties is provided with every shipment to guarantee traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and reacts with strong acids and organic solvents; therefore, it must be kept in its original sealed packaging and separated from incompatible materials.
