Description

Methylbutynol【General】 is a versatile acetylene alcohol derivative, also known as 2-Methyl-3-butyn-2-ol. This compound serves as a valuable intermediate and specialty solvent in advanced organic synthesis, prized for its unique triple bond functionality. It is particularly essential for manufacturers in the pharmaceutical, agrochemical, and fine chemical sectors seeking to build complex molecular architectures.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of active pharmaceutical ingredients (APIs), vitamins, and steroids.
• Agrochemical Synthesis: Used in the production of pesticides, herbicides, and plant growth regulators.
• Corrosion Inhibitor: Employed in metalworking fluids and acidizing formulations for industrial cleaning to protect ferrous and non-ferrous metals.
• Electroplating Additive: Acts as a brightening agent and leveler in electroplating baths for zinc, nickel, and other metals.
• Stabilizer for Chlorinated Solvents: Helps inhibit the decomposition of solvents like trichloroethylene and perchloroethylene.
• Chemical Synthesis: Serves as a precursor for other alkynols, fragrances, and specialty polymers.

Quality Control

Our Methylbutynol is produced under a stringent quality management system. Every batch undergoes comprehensive analytical testing, including GC assay and impurity profiling, to ensure it meets the high-purity standards required for industrial and synthetic applications. A Certificate of Analysis (COA) detailing purity, identity, and specific test results is provided with each shipment to guarantee traceability and compliance.

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 container tightly sealed when not in use to minimize evaporation and prevent moisture ingress.
