Description

Bis(11-Hydroxyundecyl) Disulfide, 99% is a high-purity, bifunctional organic compound featuring both a disulfide linkage and terminal hydroxyl groups. This unique molecular structure makes it a valuable intermediate for synthesizing polymers, surface-active agents, and specialty materials requiring controlled cross-linking or functionalization. It is particularly sought after by R&D chemists and production specialists in the polymer, lubricant additive, and pharmaceutical intermediate sectors.

Application

• As a key monomer or chain extender in the synthesis of polyurethanes and other specialty polymers.
• As a building block for creating novel surfactants and emulsifiers with specific hydrophilic-lipophilic balance (HLB) properties.
• In the research and development of self-assembled monolayers (SAMs) and surface modification agents.
• As a precursor for synthesizing lubricant additives that provide anti-wear and extreme pressure properties.
• In the production of cross-linked networks for hydrogels or controlled-release matrices in pharmaceutical applications.
• As an intermediate for organic synthesis, particularly in reactions where a reducible disulfide bond is required.

Quality Control

Our Bis(11-Hydroxyundecyl) Disulfide, 99% is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets the declared purity and identity specifications. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting key parameters such as assay, identity, and impurity profile.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
