Description

cis-13-Octadecenoic Acid is a monounsaturated fatty acid characterized by a cis double bond at the 13th carbon of the octadecanoic chain. This specific isomer is a valuable chemical intermediate and reference standard for research and industrial synthesis. It is essential for manufacturers and R&D laboratories in the pharmaceutical, nutritional, and specialty chemical sectors requiring high-purity fatty acid derivatives.

Application

• Pharmaceutical Intermediate: Used in the synthesis of specialized lipid-based drug molecules, prodrugs, and bioactive compounds.
• Biochemical Research: Serves as a critical reference standard and substrate in lipidomics, metabolic pathway studies, and enzyme activity assays.
• Nutritional Science: Employed in the research and development of structured lipids and specialized nutritional formulations.
• Organic Synthesis: Acts as a key chiral building block for synthesizing complex organic molecules, including surfactants and lubricant additives.
• Analytical Standard: Provides a high-purity standard for gas chromatography (GC) and high-performance liquid chromatography (HPLC) in quality control laboratories.

Quality Control

Our cis-13-Octadecenoic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chromatographic purity assays and identity confirmation, to ensure it meets stringent specifications for research and industrial use. A Certificate of Analysis (COA) detailing purity, isomer content, and other critical parameters is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere for long-term storage to prevent oxidation.
