As a Texas-based supplier, our Alcohols portfolio is curated to support manufacturing facilities across the nation, ensuring reliable delivery, continuous stock, and exceptional product integrity. We operate with a dedication to safety and logistical excellence, helping your operations run smoothly.
This compound is frequently utilized as an alternative to n-butanol in various applications due to its favorable physical properties, including its evaporation rate and solvent power. Isobutyl Alcohol 99% is highly valued in the production of lacquer solvents, automotive coatings, and architectural finishes. Its chemical characteristics make it a versatile reagent for esterification, yielding esters that are crucial in plasticizer and synthetic lubricant manufacturing. We ensure that our product meets stringent technical standards for moisture content and purity, giving your team the technical assurance necessary to maintain consistent results.
Why This Grade
While an official compendial grade is not applicable for this product, maintaining a minimum 99% concentration is critical for industrial efficiency and safety. At this high purity, the presence of water and other volatile organic impurities is minimized — a critical requirement for sensitive chemical processes. In chemical synthesis, utilizing a lower-purity solvent can introduce unwanted secondary reactions, leading to diminished product yields or poor polymer quality in coating applications. For manufacturers relying on precise chemical formulations, this 99% industrial grade prevents contamination that could compromise finished products.
Using a sub-standard grade with higher water content can cause phase separation in solvent mixtures or affect the curing process of resins and coatings. It can also lead to corrosion in manufacturing equipment and storage vessels. High-purity isobutanol is required to achieve the correct viscosity and drying characteristics in industrial paint systems. By choosing Alliance Chemical's 99% concentration, buyers avoid these operational failure modes, ensuring consistent batch-to-batch performance in every production run.

Hazmat & Shipping
Isobutyl Alcohol 99% is classified as a hazardous material for transport due to its physical and health hazards. Under federal Department of Transportation regulations, this material is shipped as UN1212, Hazard Class 3 (Flammable Liquid), Packing Group III. The designated Proper Shipping Name is Isobutanol. Because of its flammability, shipping containers must carry the appropriate Class 3 flammable liquid labels. Safe handling is guided by the GHS classification system, which assigns the signal word Danger to this product, reflecting its potential risks.
To mitigate the risks associated with GHS hazard statements H226, H315, H318, H335, and H336, operators must wear mandatory personal protective equipment (PPE). Since the chemical causes serious eye damage (H318) and skin irritation (H315), splash-resistant safety goggles, a full-face shield, and chemical-resistant nitrile or neoprene gloves are required. To prevent respiratory irritation (H335) and drowsiness or dizziness (H336) caused by inhalation of vapors, operations should be conducted under local exhaust ventilation or with a NIOSH-approved respirator. All shipping complies with DOT standards, and a comprehensive Safety Data Sheet (SDS) is provided with every order to ensure transport safety.
Handling & Storage
Storage of Isobutyl Alcohol 99% requires strict adherence to safety protocols to prevent accidental ignition or chemical degradation. It should be stored in a cool, dry, well-ventilated area away from direct sunlight, open flames, and hot surfaces, ideally at temperatures below 100 °F (38 °C). Keep containers tightly closed when not in use. This chemical is compatible with carbon steel, stainless steel, and high-density polyethylene (HDPE) containers, but can degrade certain plastics and rubbers. It is highly incompatible with strong oxidizing agents, strong acids, acid chlorides, and acid anhydrides, which can cause violent reactions.
