Description

11-Formylundecanoic Acid is a high-value, long-chain fatty acid derivative featuring a terminal formyl group, making it a versatile bifunctional building block for organic synthesis. Its unique structure is critical for introducing both carboxylic acid and aldehyde functionalities into target molecules, enabling the creation of specialized polymers, surfactants, and pharmaceutical intermediates. This compound is essential for R&D and production chemists in the fine chemical, pharmaceutical, and advanced materials sectors seeking to develop novel compounds with tailored properties.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, particularly for compounds requiring long aliphatic chains.
• Polymer Chemistry: Used as a monomer or co-monomer for producing specialty polyesters, polyamides, and other functional polymers with modified surface properties.
• Surfactant & Detergent Synthesis: Acts as a raw material for manufacturing anionic and nonionic surfactants with specific hydrophilic-lipophilic balance (HLB) values.
• Lubricant Additive: Employed in the formulation of synthetic lubricants and additives to enhance performance characteristics like viscosity and stability.
• Crosslinking Agent: Utilized in coatings, adhesives, and resin systems where the aldehyde group can participate in crosslinking reactions.
• Organic Synthesis Building Block: A valuable reagent for chain extension, macrocyclization, and the preparation of ω-functionalized fatty acid derivatives.

Quality Control

Our 11-Formylundecanoic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chromatographic purity assays and identity confirmation, to ensure it meets exacting standards for research and industrial use. A Certificate of Analysis (COA) detailing specific results for purity, appearance, and other critical parameters is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area at 2-8°C for long-term stability, as the compound is easily oxidized. Allow the container to reach ambient temperature before opening to minimize moisture condensation.
