Description

Octadecylmalonic Acid is a high-purity, long-chain dicarboxylic acid derivative, valued for its role as a versatile synthetic intermediate and building block in advanced organic synthesis. Its molecular structure, featuring both a long alkyl chain and reactive carboxyl groups, makes it a critical precursor for creating specialized surfactants, lubricant additives, and polymer modifiers. This compound is essential for R&D and production in the fine chemical, pharmaceutical, and advanced materials sectors, where precise molecular architecture is required.

Application

• Synthetic Intermediate: A key building block for the synthesis of complex organic molecules, including pharmaceuticals and agrochemicals.
• Surfactant & Detergent Precursor: Used to manufacture specialized surfactants and emulsifiers with unique hydrophobic-lipophilic balance properties.
• Lubricant & Fuel Additive Synthesis: Serves as a precursor for additives that improve viscosity, reduce friction, and enhance performance in industrial lubricants and fuels.
• Polymer Modification: Employed to introduce long alkyl chains into polymers, modifying their physical properties such as flexibility, hydrophobicity, and compatibility.
• Corrosion Inhibitor Formulation: Used in the development of corrosion-inhibiting coatings and additives for metal protection.
• Research & Development: A valuable reagent in academic and industrial R&D for exploring new chemical reactions and material properties.

Quality Control

Our Octadecylmalonic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay (HPLC), identification (IR), and impurity profiling, to ensure it meets the high standards required for industrial and research applications. A Certificate of Analysis (COA) detailing all test results 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 place at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
