Description

3,6,9,12,15,18,21,24,27,30,33-Undecaoxatetratriacontanoic Acid is a high-purity, long-chain polyether carboxylic acid derivative, serving as a critical functional intermediate and surface-active agent. Its unique molecular structure, featuring a hydrophilic polyether chain and a terminal carboxylic acid group, provides exceptional value for fine-tuning material properties and facilitating chemical synthesis. This compound is essential for researchers and manufacturers in advanced material science, pharmaceuticals, and specialty polymer production who require precise control over hydrophilicity, reactivity, and surface characteristics.

Application

• Polymer & Material Science: As a functional monomer or chain transfer agent for synthesizing amphiphilic block copolymers, hydrogels, and stimuli-responsive materials.
• Pharmaceutical Intermediates: Used in the synthesis of prodrugs, PEGylated active pharmaceutical ingredients (APIs), and drug delivery conjugates to enhance solubility and bioavailability.
• Surface Modification & Coatings: Acts as a surfactant or coupling agent to improve the dispersion of nanoparticles, modify surface wettability, and enhance adhesion in coating formulations.
• Bioconjugation & Life Sciences: Serves as a linker molecule for attaching polyethylene glycol (PEG) chains or other functional groups to proteins, peptides, or diagnostic agents.
• Specialty Chemical Synthesis: A versatile building block for creating complex surfactants, lubricant additives, and corrosion inhibitors with tailored properties.
• Electronics & Photoresists: Employed in the formulation of advanced photoresists and electronic chemicals where precise control of solubility and development is required.

Quality Control

Every batch of 3,6,9,12,15,18,21,24,27,30,33-Undecaoxatetratriacontanoic 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 high-purity standards suitable for research and industrial applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee traceability and batch-to-batch consistency.

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 nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect product stability and performance. For long-term storage, consider using desiccants or storing under an inert atmosphere.
