Description

[3-(Decylthio)-2-Hydroxypropyl]Trimethylammonium p-Toluenesulphonate is a quaternary ammonium salt with a long hydrophobic tail, functioning as a cationic surfactant and phase-transfer catalyst. This compound is valued for its ability to facilitate reactions between immiscible phases and modify surface properties in complex formulations. It is essential for manufacturers in the specialty chemical, agrochemical, and pharmaceutical intermediates sectors seeking efficient catalysts and conditioning agents.

Application

• Phase-Transfer Catalyst (PTC): Enables reactions between ionic reagents in aqueous phases and organic substrates in non-polar solvents, crucial for alkylation, esterification, and displacement reactions.
• Surfactant & Emulsifier: Acts as a cationic surfactant in specialty formulations for textiles, leather processing, and agrochemical emulsions.
• Biocide & Disinfectant Intermediate: Serves as a key building block or active component in the synthesis of quaternary ammonium-based (Quat) biocides and sanitizers.
• Corrosion Inhibitor: Used in formulations for industrial water treatment and metalworking fluids due to its film-forming and surface-active properties.
• Personal Care & Cosmetic Ingredients: Employed as a conditioning agent and antistatic component in hair care and skincare products.
• Polymer & Resin Modification: Functions as a catalyst or additive in polymerization processes and epoxy curing systems.

Quality Control

Our [3-(Decylthio)-2-Hydroxypropyl]Trimethylammonium p-Toluenesulphonate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing key parameters such as assay, moisture content, and related substances is provided and available upon request to support your quality assurance protocols.

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); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which may affect product performance and stability.
