Description

3-Ethyl-4-Octanol is a branched-chain aliphatic alcohol with the CAS registry number 19781-28-3. This versatile chemical intermediate is valued for its role in the synthesis of complex molecules, particularly in the fragrance and flavor industry where it contributes to unique organoleptic profiles. It serves as a critical building block for research chemists and production facilities in the fine chemical, agrochemical, and pharmaceutical sectors seeking to develop new compounds with specific properties.

Application

• Fragrance and Flavor Ingredient: Used as a key intermediate in the synthesis of esters and other derivatives that impart specific fruity, floral, or woody notes to perfumes and food flavorings.
• Pharmaceutical Intermediate: Serves as a chiral building block or precursor in the research and development of active pharmaceutical ingredients (APIs) and other bioactive molecules.
• Agrochemical Synthesis: Employed in the production of specialized pesticides, herbicides, and plant growth regulators where specific alkyl chain branching is required for efficacy.
• Lubricant and Plasticizer Additive: Acts as a precursor for esters used as synthetic lubricant base stocks or as co-monomers and plasticizers to modify polymer properties.
• Organic Synthesis & Research: A valuable reagent in academic and industrial laboratories for exploring new synthetic pathways, catalysis, and material science applications.
• Surface Active Agent Intermediate: Used in the manufacture of non-ionic surfactants and emulsifiers for specialty cleaning formulations and industrial processes.

Quality Control

Our 3-Ethyl-4-Octanol is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing including GC, IR, and NMR to verify identity, purity, and consistency. We provide detailed Certificates of Analysis (COA) with every shipment, ensuring full traceability and compliance with your technical requirements. Custom purity grades and specifications are available to meet specific project needs.

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 contamination.
