Description

Tetracosanedioyl Dichloride is a high-purity, long-chain diacid chloride derivative, a critical building block in advanced organic synthesis. Its primary value lies in its bifunctional reactivity, enabling the controlled formation of polymers, amides, and esters with specific chain lengths. This compound is essential for R&D and production chemists in the pharmaceutical, specialty polymer, and advanced materials sectors seeking to incorporate a C24 aliphatic spacer into target molecules.

Application

• Polymer Synthesis: Key monomer for producing specialty polyamides (nylons) and polyesters with tailored thermal and mechanical properties.
• Pharmaceutical Intermediates: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs requiring specific lipophilic character.
• Dendrimer & Macromolecule Construction: Serves as a versatile linker or core unit in the stepwise synthesis of complex, branched molecular architectures.
• Surface Modification & Coupling Agent: Functionalizes surfaces (e.g., silica, metals) or other polymers to alter wettability, adhesion, or biocompatibility.
• Liquid Crystal & Organic Semiconductor Research: Employed as a precursor for mesogenic molecules and conductive organic materials.
• Cross-linking Agent: Imparts covalent cross-links in polymer networks to enhance durability and chemical resistance.
• Lipid & Surfactant Chemistry: Used to synthesize structured lipids, bolaamphiphiles, and non-ionic surfactants for cosmetic and detergent formulations.
• Analytical Chemistry & Derivatization: Acts as a derivatization reagent for the gas chromatographic analysis of alcohols, amines, and other functional groups.

Quality Control

Our Tetracosanedioyl Dichloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including assay (HPLC), identity confirmation (IR, NMR), and impurity profiling, to ensure it meets the high-purity standards required for sensitive synthetic applications. Certificates of Analysis (COA) with lot-specific data are provided to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis. Keep away from strong bases, alcohols, and water.
