Description

Hexacosanedioic Acid is a high-purity, long-chain dicarboxylic acid with the CAS number 3365-67-1, serving as a critical building block for advanced polymer synthesis and specialty chemical manufacturing. Its extended hydrocarbon chain provides unique properties for modifying material characteristics such as flexibility, hydrophobicity, and thermal stability. This compound is essential for R&D chemists and production engineers in the polymer, lubricant, and pharmaceutical intermediate industries seeking to develop novel materials with tailored performance.

Application

• Polymer & Resin Synthesis: A key monomer for producing specialty polyamides (nylon-26,26), polyesters, and alkyd resins, imparting enhanced chain length and specific material properties.
• Lubricant & Grease Additives: Used in the formulation of synthetic esters and complex greases to improve viscosity index, thermal stability, and lubricity under extreme conditions.
• Pharmaceutical Intermediates: Serves as a precursor in the synthesis of long-chain bioactive molecules, prodrugs, and controlled-release drug delivery systems.
• Cosmetic & Personal Care Ingredients: Employed in the manufacture of high-molecular-weight emollients, wax esters, and viscosity modifiers for creams and lotions.
• Corrosion Inhibitors: Acts as a component in formulations for metal surface treatments and protective coatings.
• Academic & Industrial Research: A valuable standard and reagent for studying the physical chemistry of long-chain dicarboxylic acids and their derivatives.

Quality Control

Our Hexacosanedioic Acid is manufactured under a strict quality management system. Each batch is subjected to comprehensive analytical testing, including identification, purity assay, and impurity profiling, to ensure it meets exacting specifications for research and industrial use. Certificates of Analysis (COA) documenting all test results are provided and available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store in a cool, dry place at a controlled room temperature (15-25°C). For long-term storage, consider the use of a desiccant. Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect product quality.
