Description

2,5,8,11,14-Pentaoxahexadecan-16-Oic Acid is a high-purity, polyether-based carboxylic acid derivative, valued for its unique combination of hydrophilic polyether chains and a terminal reactive acid group. This bifunctional structure makes it an essential intermediate and functional additive in advanced material synthesis. It is primarily sought by R&D and production teams in the pharmaceutical, polymer, and specialty chemical industries for creating tailored compounds with specific solubility and surface properties.

Application

• Pharmaceutical Intermediate: Used in the synthesis of prodrugs, PEGylated active pharmaceutical ingredients (APIs), and drug delivery systems to enhance solubility and bioavailability.
• Polymer Modification: Serves as a functional monomer or chain terminator in the production of polyesters, polyurethanes, and other specialty polymers to introduce hydrophilic segments.
• Surface-Active Agent: Acts as a key component in the formulation of non-ionic surfactants, emulsifiers, and dispersants for coatings, inks, and agrochemicals.
• Crosslinking Agent: Utilized in the creation of hydrogels and crosslinked polymer networks for biomedical and separation technology applications.
• Chemical Synthesis Building Block: Employed in organic synthesis for attaching polyether spacers to various molecules, facilitating further conjugation reactions.
• Lubricant & Fuel Additive Precursor: Used to synthesize advanced polyether-based additives that improve lubricity and performance in industrial fluids.
