Description

Trimethylhexanol is a branched-chain primary alcohol, also known by its CAS number 1331-39-1. This versatile chemical intermediate is valued for its hydrophobic properties and ability to impart specific performance characteristics in formulations. It is a critical raw material for manufacturers in the coatings, plasticizers, and specialty chemical sectors seeking to enhance product durability and functionality.

Application

• Plasticizer Precursor: A key intermediate in the synthesis of specialized phthalate and trimellitate plasticizers for PVC and other polymers.
• Synthetic Lubricants & Hydraulic Fluids: Used to produce esters that serve as high-performance base stocks and additives, offering excellent thermal stability and low-temperature properties.
• Coating Resins & Additives: Employed in the manufacture of alkyd resins and as a modifying agent to improve flow, leveling, and hydrophobicity in paints and varnishes.
• Surfactants & Emulsifiers: Acts as a hydrophobic building block for nonionic surfactants used in industrial and institutional cleaning formulations.
• Flavor & Fragrance Ingredient: Serves as a starting material or intermediate for the synthesis of certain aroma chemicals.
• Chemical Synthesis: A valuable reagent and intermediate in organic synthesis for pharmaceuticals, agrochemicals, and other fine chemicals.

Quality Control

Our Trimethylhexanol is produced under a strict quality management system to ensure batch-to-batch consistency and reliability. Quality is verified through comprehensive analytical testing including gas chromatography (GC) for assay and impurity profiling. A Certificate of Analysis (COA) detailing purity, identity, and physical properties is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials such as strong oxidizing agents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to minimize moisture absorption and prevent evaporation.
