Description

1-Mercapto-2-Propanol is a versatile organosulfur compound featuring both a thiol and a hydroxyl functional group, making it a valuable intermediate for chemical synthesis. Its bifunctional nature allows it to act as a key building block for pharmaceuticals, agrochemicals, and specialty polymers, where it introduces sulfur-containing moieties or serves as a chain transfer agent. This product is essential for R&D laboratories and industrial manufacturers in the fine chemical, pharmaceutical, and polymer industries seeking reliable, high-purity raw materials.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring thioether linkages or as a precursor for cysteine analogs.
• Polymer & Resin Modifier: Acts as a chain transfer agent (CTA) in radical polymerizations to control molecular weight and as a cross-linking agent in epoxy and polyurethane systems.
• Agrochemical Synthesis: Serves as a key intermediate in the production of certain herbicides, fungicides, and insecticides.
• Chemical Synthesis Reagent: Employed in organic synthesis for thiol-ene "click" chemistry, nucleophilic additions, and as a protecting group for alcohols.
• Rubber & Elastomer Industry: Functions as a vulcanization accelerator or modifier to enhance processing and physical properties.
• Flavor & Fragrance Ingredient: Used as a precursor for sulfur-containing flavor compounds, contributing to meaty or roasted notes.
• Surface Active Agents: Can be utilized to synthesize surfactants and detergents with specific hydrophilic-lipophilic balance (HLB) properties.
• Research & Development: A valuable tool compound in academic and industrial research for exploring new synthetic methodologies and material science.

Quality Control

Our 1-Mercapto-2-Propanol is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay, identity confirmation, and impurity profiling, to ensure it meets stringent specifications for industrial and research applications. A Certificate of Analysis (COA) detailing purity, physical properties, and test results is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong oxidizing agents. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and maintain product integrity. Recommended storage temperature is 2-8°C for long-term stability.
