Description

Heneicosanedioic Acid, 8,14-Dihydroxy-2,2,20,20-Tetramethyl- is a high-purity, long-chain diacid derivative featuring strategically positioned hydroxyl and gem-dimethyl groups. This unique molecular architecture makes it a valuable advanced intermediate for synthesizing specialized polymers, high-performance lubricants, and complex organic molecules. It is primarily sought by R&D chemists and process engineers in the pharmaceutical, specialty polymer, and advanced materials sectors for its potential to impart specific thermal and mechanical properties.

Application

• Pharmaceutical Intermediate: Serves as a key building block for the synthesis of novel active pharmaceutical ingredients (APIs), particularly those requiring rigid, lipophilic backbones.
• Specialty Polymer Monomer: Used in the production of high-performance polyamides, polyesters, and polyurethanes, contributing to enhanced thermal stability, crystallinity, and mechanical strength.
• Lubricant & Grease Additive Synthesis: Acts as a precursor for synthesizing complex esters and thickeners used in high-temperature and extreme-pressure lubricant formulations.
• Macrocyclic Compound Synthesis: Utilized in the construction of large-ring compounds, including crown ether analogs and molecular receptors, due to its pre-organized diacid structure.
• Surface Coating Resins: Incorporated into alkyd or polyester resins to modify flexibility, adhesion, and chemical resistance in industrial coatings.
• Academic & Industrial Research: A valuable tool for chemical research in organic synthesis, materials science, and supramolecular chemistry.

Quality Control

Our Heneicosanedioic Acid, 8,14-Dihydroxy-2,2,20,20-Tetramethyl- is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity, IR and NMR for structural confirmation, and Karl Fischer titration for moisture content. We provide a detailed Certificate of Analysis (COA) with each shipment to ensure full traceability and compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This compound is moisture-sensitive (hygroscopic); keep the container tightly sealed under an inert atmosphere such as nitrogen or argon for long-term storage to prevent oxidation and absorption of moisture.
