Description

Docosyl-Triethylenetetraminepentaacetic Acid is a high-purity, long-chain derivative of the versatile chelating agent DTPA (diethylenetriaminepentaacetic acid). This compound matters for its enhanced lipophilicity and strong metal-chelating capacity, making it uniquely effective in specialized formulations where standard chelators are insufficient. Industries requiring advanced stabilization, decontamination, or metal ion control in non-aqueous or complex matrices will find this product critical for their processes.

Application

• Specialty Chemical Synthesis: Acts as a key intermediate or functional additive in the production of high-performance surfactants, lubricant additives, and polymer stabilizers.
• Pharmaceutical & Cosmetic Formulations: Used as a potent chelating agent in topical creams, ointments, and other lipid-based delivery systems to enhance stability and shelf-life by sequestering pro-oxidant metal ions.
• Industrial Decontamination: Employed in specialized cleaning and decontamination formulations for nuclear or heavy metal industries, where its long alkyl chain improves solubility in organic solvents for surface treatment.
• Research & Development: Serves as a model compound or reagent in academic and industrial R&D for studying metal-ligand interactions in hydrophobic environments and developing new analytical methods.
• Oilfield Chemicals: Potential application as a scale inhibitor or metal ion controller in enhanced oil recovery processes where compatibility with organic phases is required.

Quality Control

Our Docosyl-Triethylenetetraminepentaacetic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications and internal standards. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance and stability.
