Description

Butanol CAS NO 71-36-3 is a primary alcohol and a versatile four-carbon solvent with significant industrial importance. Its balanced properties of moderate polarity, volatility, and solvent power make it a critical intermediate and formulation component across numerous sectors. This chemical is essential for manufacturers in the coatings, plastics, chemical synthesis, and specialty chemicals industries seeking a reliable and effective solvent or raw material.

Application

• Solvent for Coatings and Inks: A key component in lacquers, varnishes, and printing inks, where it improves flow, gloss, and drying characteristics.
• Chemical Intermediate: Used in the synthesis of butyl acrylate, butyl acetate, glycol ethers, and other esters, which are vital for polymers and plasticizers.
• Extraction Agent: Employed in the purification and extraction of pharmaceuticals, natural products, and other chemicals.
• Industrial Cleaner: An effective ingredient in degreasers and cleaning formulations for metal surfaces and precision equipment.
• Plasticizer and Additive: Acts as a co-solvent and viscosity modifier in polymer and resin systems.
• Fuel and Biofuel Additive: Used as a blending component or a precursor for oxygenated fuel additives.

Quality Control

Our Butanol is produced and tested under stringent quality management systems to ensure batch-to-batch consistency and reliability. We provide comprehensive Certificates of Analysis (COA) detailing purity, identity, and impurity profiles. Our quality commitment aligns with major industrial standards, and we support compliance with relevant global regulatory frameworks such as REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its highly volatile nature and compatibility as a strong acid/organic solvent, keep away from incompatible materials such as strong oxidizing agents. Recommended storage temperature is 15-25°C.
