Description

tert-Nonyl Mercaptan is a branched-chain alkyl mercaptan widely utilized as a chain transfer agent and polymerization modifier. Its primary value lies in its ability to efficiently control polymer molecular weight and structure, which is critical for achieving desired material properties in synthetic processes. This chemical is essential for manufacturers in the polymer, rubber, and specialty chemical industries seeking to fine-tune product performance and consistency.

Application

• Polymerization Modifier: Acts as a highly effective chain transfer agent (CTA) in the production of synthetic rubbers like styrene-butadiene rubber (SBR) and polybutadiene rubber (PBR).
• Molecular Weight Regulator: Used to control the molecular weight and polydispersity of acrylic polymers, vinyl acetate polymers, and other free-radical polymerizations.
• Lubricant & Fuel Additive Intermediate: Serves as a key intermediate in the synthesis of extreme pressure (EP) additives for lubricants and anti-wear agents.
• Pharmaceutical & Agrochemical Synthesis: Employed as a building block or sulfur source in the synthesis of complex organic molecules for pharmaceutical and crop protection applications.
• Odorant & Leak Detection: Used in trace amounts as an odorant for natural gas and LPG due to its strong, distinctive smell, aiding in leak detection.
• Surface Modifier: Functions as a surface-active agent or modifier in specialty coatings and material surface treatments.

Quality Control

Our tert-Nonyl Mercaptan is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and assay, to ensure it meets precise specifications for its intended industrial applications. Certificates of Analysis (COA) documenting identity, purity, and key physical properties are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation of quality. Keep away from strong oxidizing agents.
