Description

Dimyristyl Disulfide is a high-purity, synthetic organic compound belonging to the dialkyl disulfide class, characterized by its two myristyl (tetradecyl) chains. This chemical is valued for its role as a versatile intermediate and performance additive, offering unique chemical functionality for synthesis and material modification. It is primarily sought after by manufacturers in the lubricant, polymer, and specialty chemical industries for applications requiring sulfur-based chemistry.

Application

• Lubricant & Grease Additive: Functions as an extreme pressure (EP) and anti-wear agent, enhancing the performance and longevity of industrial and automotive lubricants.
• Polymer Modification & Crosslinking Agent: Used in the synthesis and vulcanization of specialty rubbers and elastomers to improve thermal stability and mechanical properties.
• Chemical Intermediate: Serves as a key building block in organic synthesis for pharmaceuticals, agrochemicals, and other fine chemicals requiring disulfide linkages.
• Metalworking Fluids: Incorporated into cutting oils and coolants to provide lubrication and reduce tool wear during machining operations.
• Corrosion Inhibitor Precursor: Used in formulations to develop protective coatings and additives that prevent oxidation and corrosion on metal surfaces.
• Personal Care & Cosmetics: Employed as a conditioning agent and viscosity modifier in high-end cosmetic formulations, though subject to strict purity requirements.

Quality Control

Our Dimyristyl Disulfide is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chromatography (HPLC/GC) and spectroscopic methods, to ensure high chemical purity and consistency. A Certificate of Analysis (COA) detailing purity, identity, and physical parameters is provided with every shipment to guarantee compliance with your technical specifications.

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 easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) is recommended to preserve stability. Keep away from strong oxidizing agents and heat sources.
