Description

3,6,9,12,15,18,21,24-Octaoxaheptatriacontanoic Acid is a high-purity, long-chain polyether carboxylic acid derivative, valued for its unique amphiphilic properties and excellent solubility profile. This compound is a critical functional intermediate and surfactant, enabling precise formulation control and enhanced performance in advanced chemical synthesis. It is primarily utilized by manufacturers in the pharmaceutical, polymer, and specialty chemical industries for applications requiring non-ionic surfactant behavior, phase transfer catalysis, or as a building block for complex macromolecules.

Application

• Pharmaceutical Intermediate: Used in the synthesis of drug delivery systems, particularly for PEGylated (polyethylene glycol) active pharmaceutical ingredients (APIs) to improve solubility and bioavailability.
• Polymer & Material Science: Serves as a functional monomer or surfactant in the production of polyurethanes, epoxy resins, and other specialty polymers to modify surface properties and stability.
• Specialty Surfactant & Emulsifier: Acts as a high-performance, non-ionic surfactant in demanding formulations for agrochemicals, coatings, and industrial cleaners.
• Phase Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases in organic synthesis, improving yield and efficiency.
• Lubricant & Additive Precursor: Employed in the development of advanced synthetic lubricants and fuel additives due to its thermal stability and low volatility.
• Cosmetic & Personal Care Formulations: Used as a mild surfactant or emulsifying agent in high-end skincare products.

Quality Control

Every batch of 3,6,9,12,15,18,21,24-Octaoxaheptatriacontanoic Acid is manufactured under a strict quality management system. Our products undergo rigorous analytical testing, including HPLC, NMR, and titration methods, to ensure compliance with exacting purity and consistency standards. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with each shipment to support your quality assurance protocols.

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 material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture.
