Description

2,2'-[Octane-1,8-Diylbis(Thio)]Bisethanol is a high-purity sulfur-containing diol compound, valued for its dual thioether and terminal hydroxyl functionalities. This structure makes it a versatile intermediate and chain transfer agent, offering unique properties in polymerization and surface modification processes. It is essential for manufacturers in the polymer, lubricant additive, and specialty chemical industries seeking to enhance product performance and stability.

Application

• Polymer Industry: Acts as a chain transfer agent (CTA) or cross-linking agent in the synthesis of polyurethanes, polyesters, and epoxy resins to modify molecular weight and introduce sulfur linkages.
• Lubricant & Fuel Additives: Serves as a key intermediate for manufacturing multifunctional additives that improve extreme pressure (EP) properties, anti-wear performance, and oxidation stability.
• Surface Active Agents: Used in the production of specialty surfactants and emulsifiers for demanding industrial formulations.
• Metal Working Fluids: Incorporated as a building block for corrosion inhibitors and lubricity enhancers in cutting and grinding fluids.
• Pharmaceutical Intermediates: Employed in the synthesis of complex molecules where a lipophilic, sulfur-bridged diol moiety is required.
• Adhesive & Sealant Formulations: Functions as a modifier to improve flexibility, adhesion, and chemical resistance in advanced adhesive systems.

Quality Control

Our 2,2'-[Octane-1,8-Diylbis(Thio)]Bisethanol is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure it meets high-purity standards and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and should be kept under an inert atmosphere (e.g., nitrogen) after opening to prevent oxidation and moisture absorption.
