Description

2-Butanol (CAS NO 78-92-2), also known as sec-butyl alcohol, is a versatile four-carbon secondary alcohol with significant industrial utility. Its primary value lies in its dual functionality as a solvent and a chemical intermediate, offering a favorable balance of solvency, volatility, and reactivity. This compound is essential for manufacturers in sectors such as coatings, chemical synthesis, and fragrance production, where its properties are leveraged to improve processes and product performance.

Application

• Industrial Solvent: A key component in lacquers, paints, varnishes, and industrial cleaning formulations due to its effective solvency for resins and oils.
• Chemical Synthesis Intermediate: Used in the production of methyl ethyl ketone (MEK), a vital industrial solvent, via controlled oxidation.
• Extraction Agent: Employed in the purification and extraction processes within the pharmaceutical and fine chemical industries.
• Fragrance and Flavor Ingredient: Serves as a carrier solvent and a starting material for esters used in fragrances and food flavorings.
• Coalescing Aid: Used in latex and water-based coating formulations to help polymer particles fuse together, forming a continuous film.
• Printing Inks: Acts as a solvent and flow-control agent in various ink systems.

Quality Control

Our 2-Butanol is manufactured under a stringent quality management system to ensure batch-to-batch consistency and reliability. We provide comprehensive quality documentation, including detailed Certificates of Analysis (COA) for each shipment, which verify key parameters such as purity, identity, and impurity profiles. Our commitment to quality assurance supports your compliance needs for industrial and specialty applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and ignition points. 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 15-25°C.
