Description

9,9-Diethoxynonanoic Acid Ethyl Ester is a high-purity, versatile bifunctional chemical intermediate featuring both a protected aldehyde and an ester group. This compound is valued for its role in sophisticated organic synthesis, enabling the controlled introduction of long-chain aldehyde precursors into target molecules. It is primarily sought by R&D chemists and process development teams in the pharmaceutical, agrochemical, and specialty fragrance industries for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of prostaglandin analogs, lipid mediators, and other bioactive molecules with long aliphatic chains.
• Agrochemical Synthesis: Used in the production of advanced pesticides and plant growth regulators requiring specific carbon chain length and functional group compatibility.
• Specialty Fragrance & Flavor Precursor: Serves as a starting material for the synthesis of macrocyclic musks and other high-value aroma chemicals where the diethoxy acetal group allows for controlled release of the aldehyde.
• Polymer & Material Science: Employed as a monomer or cross-linking agent in the development of specialty polyesters and functional polymers with tailored properties.
• Organic Synthesis Reagent: Utilized in academic and industrial research for homologation reactions and as a protected form of 9-oxononanoic acid in multi-step synthetic sequences.
• Lubricant & Fuel Additive Intermediate: Acts as a precursor for synthesizing ester-based additives that modify viscosity and performance characteristics.

Quality Control

Our 9,9-Diethoxynonanoic Acid Ethyl Ester is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high chemical purity and identity confirmation. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee batch-to-batch consistency and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong bases and incompatible materials such as strong oxidizing agents. The container should be kept tightly sealed to prevent moisture absorption and potential degradation.
