Isodecanol, identified by CAS number 25339-17-7, is a high-purity, branched-chain primary alcohol containing ten carbon atoms. Unlike its linear counterpart, n-decanol, isodecanol is a complex mixture of isomers—primarily dimethyl-octanols and methyl-nonanols—produced via the hydroformylation (Oxo process) of nonene isomers followed by hydrogenation. This branching imparts unique physical properties, such as a significantly lower pour point and enhanced solubility in organic media, which are critical for specialized industrial applications.
As a clear, colorless, and relatively viscous liquid with a characteristic mild odor, isodecanol serves as a versatile chemical intermediate. Its primary value lies in its ability to undergo esterification, ethoxylation, and sulfation to produce high-performance derivatives. It is favored in industrial chemistry for its low volatility, high boiling point, and excellent stability. Because it is less prone to crystallization than linear Alcohol, it remains fluid and workable in cold-weather environments, making it a staple feedstock in the production of plasticizers, surfactants, and specialty lubricants.
