Description

10-Undecenoyl Chloride is a versatile, high-purity acid chloride derivative of 10-undecenoic acid, serving as a critical building block in advanced organic synthesis. Its reactive acyl chloride functional group makes it an essential reagent for introducing the undecylenoyl moiety into target molecules, enabling the creation of specialized polymers, pharmaceuticals, and fine chemicals. This compound is particularly valuable for R&D and production teams in the pharmaceutical, agrochemical, and specialty polymer industries seeking to develop novel compounds with specific chain-length properties.

Application

• Pharmaceutical Intermediate: Key starting material for synthesizing active pharmaceutical ingredients (APIs) and prodrugs, particularly those requiring a long-chain fatty acid derivative.
• Polymer Chemistry: Monomer or modifying agent for producing specialty polyamides, polyesters, and other polymers with tailored hydrophobic or cross-linking characteristics.
• Agrochemical Synthesis: Used in the manufacture of plant growth regulators, fungicides, and herbicides where the undecylenoyl chain influences bioavailability and activity.
• Lubricant & Surfactant Additives: Intermediate for creating high-performance ester-based lubricant additives and specialty surfactants.
• Flavor & Fragrance Industry: Building block for the synthesis of specific musk analogs and other fragrance compounds.
• Bioconjugation & Linker Chemistry: Useful in biochemical research for labeling proteins or creating cleavable linkers due to its reactive site and terminal alkene functionality.
• Organic Synthesis Reagent: Employed in Friedel-Crafts acylation, esterification, and amidation reactions to install the C11 acyl group.

Quality Control

Our 10-Undecenoyl Chloride is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay by titration, identity confirmation via FT-IR, and impurity profiling by GC or HPLC. A detailed Certificate of Analysis (COA) documenting purity, physical properties, and test results is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 2-8°C (refrigerated) or as specified on the label. Due to its hygroscopic and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent hydrolysis. Keep away from strong bases, oxidizers, and moisture.
