Description

4,7,10,13,16-Pentamethyl-5,8,11,14,17-Pentaoxa-2-Thiaicosan-19-Ol is a specialized polyether-thiol compound with a unique molecular architecture, serving as a versatile intermediate and functional additive. Its value lies in its ability to act as a ligand, surfactant, or solubilizing agent due to its combination of ether linkages, a thioether group, and a terminal hydroxyl group. This chemical is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require precise molecular control for synthesis, formulation, and surface modification.

Application

• Pharmaceutical Intermediate: Used in the synthesis of complex drug molecules, particularly where polyether chains are needed for solubility or targeted delivery.
• Ligand for Catalysis: Acts as a chelating or coordinating agent in transition metal catalysis for organic synthesis reactions.
• Surface-Active Agent: Functions as a non-ionic surfactant or emulsifier in specialty formulations due to its amphiphilic structure.
• Polymer Modification: Serves as a chain transfer agent or functional monomer to introduce thioether and polyether segments into polymers.
• Agrochemical Formulations: Employed as an adjuvant or penetrant to enhance the efficacy and stability of pesticide and herbicide formulations.
• Chemical Synthesis Building Block: Provides a multifunctional scaffold for constructing more complex molecular architectures in research and development.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is analyzed to confirm identity, purity, and consistency. Certificates of Analysis (COA) detailing specific results for assay, impurities, and physical parameters are available upon request. We adhere to cGMP principles where applicable to support our customers in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); keep the container tightly sealed under an inert atmosphere such as nitrogen or argon to prevent degradation from moisture uptake.
