Description

13-Octadecenoic Acid is a monounsaturated fatty acid of significant industrial interest. This compound serves as a versatile intermediate and building block in the synthesis of specialty chemicals and advanced materials. It is particularly valuable for manufacturers in the oleochemical, pharmaceutical, and personal care industries seeking to develop or modify product formulations.

Application

• Oleochemical Intermediate: A key raw material for producing derivatives like esters, amides, and salts used in lubricants, plasticizers, and surfactants.
• Pharmaceutical Synthesis: Employed as a chiral synthon or intermediate in the research and development of active pharmaceutical ingredients (APIs).
• Personal Care & Cosmetics: Used in the formulation of emollients, moisturizers, and other specialty ingredients for skin and hair care products.
• Polymer & Resin Modification: Acts as a modifier or additive to alter the flexibility, hydrophobicity, or processing characteristics of polymers.
• Research & Development: Serves as a standard or reagent in analytical chemistry, biochemistry, and material science research.
• Food-Grade Additive Precursor: Can be used in the synthesis of food-grade emulsifiers or release agents, subject to appropriate purity and regulatory compliance.

Quality Control

Our 13-Octadecenoic Acid is produced and tested under a rigorous quality management system. Each batch is analyzed to ensure it meets stringent specifications for identity, purity, and composition. A comprehensive Certificate of Analysis (COA) detailing assay, isomer content, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen) to preserve quality and stability.
