Description

Propargyl Alcohol is a versatile and reactive primary alcohol characterized by its terminal alkyne functional group. This unique structure makes it a valuable bifunctional building block in organic synthesis, serving as a precursor for pharmaceuticals, agrochemicals, and corrosion inhibitors. It is essential for industries requiring high-purity intermediates for fine chemical manufacturing, metal surface treatment, and specialty polymer production. Global suppliers rely on consistent quality and reliable supply chains for this critical raw material.

Application

• Chemical Synthesis Intermediate: A key precursor in the production of pharmaceuticals, vitamins (like Vitamin A), and agrochemicals.
• Corrosion Inhibitor: Used in acid pickling and cleaning formulations for ferrous and non-ferrous metals, particularly in oilfield and industrial water systems.
• Electroplating Additive: Acts as a brightening and leveling agent in electroplating baths for zinc, nickel, and other metals.
• Stabilizer and Intermediate: Employed in the synthesis of stabilizers for polymers and as an intermediate for specialty chemicals like propargyl bromide.
• Soil Fumigant and Nematicide: Used as an intermediate in the manufacture of certain soil fumigants and nematicidal agents.
• Crosslinking Agent: Utilized in the production of resins and polymers where its alkyne group can participate in crosslinking reactions.

Quality Control

Our Propargyl Alcohol is manufactured under a stringent quality management system. Every batch undergoes rigorous analytical testing, including Gas Chromatography (GC) for purity and identity confirmation, to ensure it meets exacting specifications. A comprehensive Certificate of Analysis (COA) detailing purity, water content, and other critical parameters is provided with each shipment to guarantee traceability and compliance with your requirements.

Storage

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