Description

Rac 10,14-Dimethylpentadecyl Isobutyrate is a branched-chain fatty acid ester, specifically the isobutyric acid ester of a dimethyl-substituted pentadecanol. This compound is valued for its role as a versatile chemical intermediate and a high-purity standard in analytical and synthetic chemistry. It is primarily sought by manufacturers in the fragrance, flavor, and specialty chemical industries for creating unique organoleptic profiles and complex molecular architectures. Its defined structure makes it a critical reference material for quality control and research applications.

Application

• Fragrance & Flavor Ingredient: Serves as a building block or modifier in the synthesis of novel musk-like, woody, or amber notes for perfumes, cosmetics, and food flavorings.
• Chemical Intermediate: Used in organic synthesis for pharmaceuticals, agrochemicals, and liquid crystals, leveraging its reactive ester group and specific alkyl chain.
• Reference Standard: Employed as a high-purity analytical standard in Gas Chromatography (GC) and Mass Spectrometry (MS) for method development and quality assurance.
• Lubricant & Plasticizer Component: Acts as a specialty additive or base fluid in high-performance lubricants and polymer formulations, contributing to low-temperature properties and stability.
• Surfactant & Emulsifier Synthesis: Provides a hydrophobic backbone for the production of non-ionic surfactants used in industrial and personal care applications.
