Description

tert-Pentadecanethiol CAS NO 26544-03-6 is a high-purity, branched-chain alkanethiol characterized by its tertiary thiol functional group. This compound is a critical intermediate and functional additive valued for its ability to modify surface properties and act as a chain transfer agent in polymerization processes. It is essential for manufacturers and R&D laboratories in the polymer, specialty chemical, and materials science sectors seeking to fine-tune molecular weight, introduce specific functionalities, or create self-assembled monolayers.

Application

• Polymerization Chain Transfer Agent (CTA): Used to control molecular weight and polydispersity in radical polymerizations, including the production of acrylics, styrenics, and other specialty polymers.
• Surface Modification & Self-Assembled Monolayers (SAMs): Serves as a key ligand for creating hydrophobic or functionalized surfaces on gold, silver, and other metals for sensor, electronic, and corrosion-resistant coating applications.
• Lubricant & Fuel Additive: Functions as an extreme pressure (EP) additive and anti-wear agent in advanced lubricant formulations and as a stabilizer in fuel systems.
• Pharmaceutical & Agrochemical Intermediate: Utilized as a building block in the synthesis of more complex molecules requiring a shielded thiol group.
• Rubber & Elastomer Processing: Acts as a peptizing agent or vulcanization modifier to improve processing characteristics and final product properties.
• Nanoparticle Capping Agent: Employed to stabilize metal and semiconductor nanoparticles, controlling their growth, dispersion, and surface chemistry.

Quality Control

Our tert-Pentadecanethiol is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) and Nuclear Magnetic Resonance (NMR) spectroscopy, to ensure high purity and consistent performance. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its easily oxidized nature, minimize headspace and exposure to air after opening.
