Description

11-Fluoro-3-Methylundecanoic Acid is a specialized fluorinated fatty acid derivative that serves as a valuable building block in advanced organic synthesis. Its unique structure, featuring a fluorine atom and a methyl branch on an extended alkyl chain, makes it a critical intermediate for introducing lipophilic and metabolically stable motifs into target molecules. This compound is essential for research and development chemists in the pharmaceutical and agrochemical industries, where it is used to modulate the physicochemical properties and biological activity of novel compounds.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel active pharmaceutical ingredients (APIs), particularly in medicinal chemistry programs targeting metabolic diseases and central nervous system (CNS) disorders.
• Agrochemical Research: Used in the development of new herbicides, fungicides, and plant growth regulators, where the fluorine atom can enhance bioavailability and environmental stability.
• Liquid Crystal & Material Science: Serves as a precursor for fluorinated mesogens and other advanced materials requiring specific dielectric and surface properties.
• Biochemical Probe Synthesis: Employed in creating labeled fatty acid analogs and other probes for studying lipid metabolism and protein-lipid interactions in biological systems.
• Organic Synthesis Reagent: Acts as a versatile synthon for preparing more complex fluorinated compounds through reactions at the carboxylic acid group or along the alkyl chain.

Quality Control

We maintain a rigorous quality management system to ensure batch-to-batch consistency and high purity for our fluorinated intermediates. Our standard grade for 11-Fluoro-3-Methylundecanoic Acid typically meets a purity specification of ≥95% (by HPLC), with detailed impurity profiling available. A comprehensive Certificate of Analysis (COA) is provided with each shipment, documenting identity, purity, and relevant physical characteristics. We support custom synthesis and can tailor purity grades to meet specific project requirements under cGMP or ISO 9001 guidelines.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. For long-term storage, we recommend maintaining the product at 2-8°C under an inert atmosphere to preserve stability. The container should be kept tightly sealed to prevent moisture absorption.
