Description

Petroselinic Acid CAS NO 593-39-5 is a monounsaturated ω-12 fatty acid, specifically the cis-6-octadecenoic acid isomer. This compound serves as a valuable specialty chemical intermediate and a model compound for studying lipid oxidation and metabolism. It is particularly relevant for manufacturers and researchers in the oleochemical, pharmaceutical, and cosmetic industries seeking high-purity fatty acid derivatives. Its unique structure offers distinct reactivity compared to more common fatty acids like oleic acid.

Application

• Chemical Synthesis Intermediate: Used in the production of specialized surfactants, lubricants, and polymer additives.
• Pharmaceutical Research: Acts as a reference standard and starting material for synthesizing bioactive lipid molecules and studying metabolic pathways.
• Cosmetic & Personal Care Formulations: Incorporated into emollients and specialty esters for skin-conditioning products.
• Nutritional & Biochemical Studies: Serves as a substrate in research on fatty acid desaturation and oxidation mechanisms.
• Analytical Standard: Employed as a high-purity calibrant in gas chromatography (GC) and mass spectrometry (MS) for lipid analysis.
• Industrial Lubricant Formulation: Used in the development of synthetic esters with specific low-temperature and oxidative stability properties.

Quality Control

Our Petroselinic Acid is produced under a strict quality management system. Each batch is analyzed to ensure high chemical purity and identity confirmation. Certificates of Analysis (COA) documenting key parameters such as assay, identity, and impurity profile are provided and available upon request. We can support compliance requirements for research and industrial applications.

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). Due to its property of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize degradation. Keep away from strong oxidizers.
