Description

2-(14-Carboxytetradecyl-n-Ethyl Maleic Ester)-2-Ethyl-4,4-Dimethyl-3-Oxazolidinyl Oxyl is a specialized nitroxide radical compound, a member of the stable TEMPO (2,2,6,6-Tetramethylpiperidin-1-oxyl) derivative family. This compound is valued for its role as a highly effective and selective mediator in controlled radical polymerization processes, enabling the precise synthesis of polymers with tailored architectures. It is essential for R&D and production in advanced polymer chemistry, serving industries focused on high-performance materials, specialty coatings, and biomedical applications where controlled molecular weight and low polydispersity are critical.

Application

• Nitroxide-Mediated Polymerization (NMP): Acts as a controlling agent for the synthesis of well-defined block copolymers, gradient copolymers, and other complex polymer architectures with narrow molecular weight distributions.
• Advanced Material Synthesis: Used in the development of specialty polymers for coatings, adhesives, and dispersants that require specific thermal or mechanical properties.
• Biomedical Polymer Research: Facilitates the creation of biocompatible and biodegradable polymers for drug delivery systems, hydrogels, and implantable medical devices.
• Surface Modification: Employed to graft polymer brushes onto various substrates (e.g., silicon, gold, polymers) for creating smart surfaces with controlled wettability, lubrication, or anti-fouling properties.
• Organic Synthesis & Catalysis: Serves as a stable radical catalyst or oxidant in selective organic transformations and as a spin label in spectroscopic studies.
