Description

2-Mercaptopropanol CAS NO 3001-64-7 is a versatile organosulfur compound featuring both a thiol and a hydroxyl functional group. This bifunctional nature makes it a valuable intermediate and reagent in organic synthesis and industrial applications. It is primarily sought after by manufacturers in the pharmaceutical, polymer, and specialty chemical sectors. Its reactivity is leveraged in the production of various fine chemicals and as a chain transfer agent or modifier.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and drug candidates, particularly those requiring thioether linkages or chiral centers.
• Polymer Chemistry: Acts as a chain transfer agent in radical polymerizations and as a modifier for epoxy resins and polyurethanes to impart specific properties.
• Chemical Synthesis: Serves as a key building block for synthesizing heterocyclic compounds, ligands for metal catalysis, and other specialty organosulfur chemicals.
• Crosslinking Agent: Utilized in the formulation of adhesives, sealants, and coatings where its dual functionality can promote crosslinking.
• Analytical Reagent: Employed in biochemical research and as a derivatization agent in analytical chemistry for the detection of specific functional groups.
• Rubber and Plastic Additive: Functions as an antioxidant precursor or a stabilizer due to its thiol group's ability to scavenge free radicals.

Quality Control

Our 2-Mercaptopropanol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by GC or titration and impurity profiling, to ensure it meets defined specifications and is suitable for its intended industrial use. 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 properties of being easily oxidized (store under inert atmosphere) and highly volatile, it is recommended to keep the container under an inert gas blanket (e.g., nitrogen) and at a controlled room temperature (15-25°C).
