Description

Mercaptoacetic Acid Propyl Ester is an organosulfur compound valued for its role as a versatile intermediate and functional additive in specialty chemical synthesis. Its unique structure, featuring both a thiol and an ester group, makes it a critical reagent for introducing sulfur-containing moieties and modifying polymer properties. This product is essential for manufacturers in the polymer, agrochemical, and pharmaceutical industries seeking to develop materials with specific characteristics like cross-linking, adhesion, or controlled reactivity.

Application

• Polymer Modification & Cross-linking Agent: Used in the production and curing of specialty polymers, including acrylic resins and rubber, to enhance properties like elasticity, thermal stability, and adhesion.
• Chemical Intermediate for Agrochemicals: Serves as a key building block in the synthesis of certain herbicides, fungicides, and plant growth regulators.
• Pharmaceutical Intermediate: Employed in the research and development of active pharmaceutical ingredients (APIs), particularly those requiring thiol-ester functionalities.
• Lubricant & Fuel Additive Precursor: Acts as an intermediate for manufacturing extreme pressure additives and antioxidants used in industrial lubricants and fuels.
• Surface Treatment & Metalworking Fluids: Utilized in formulations for metal surface treatment and as a component in cutting and grinding fluids for its lubricity and anti-wear properties.
• Adhesive & Sealant Formulations: Incorporated to improve the curing profile, flexibility, and bond strength of various adhesive and sealant systems.

Quality Control

Our Mercaptoacetic Acid Propyl Ester is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including Gas Chromatography (GC) for purity and identity confirmation, to ensure it meets precise specifications. Certificates of Analysis (COA) with detailed batch-specific results are provided to guarantee consistent quality, traceability, and compliance with your technical requirements.

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 and bases. Due to its highly volatile and light-sensitive nature, containers should be kept tightly sealed and under an inert atmosphere (e.g., nitrogen) for long-term storage to maintain purity and prevent degradation. Recommended storage temperature: 2-8°C.
