Description

11,11-Dimethoxyundec-1-Ene is a specialized organic compound featuring a terminal alkene and a protected aldehyde functionality. This unique structure makes it a valuable versatile building block in advanced organic synthesis, particularly for the construction of complex molecules. It is primarily sought after by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and fragrance industries for creating novel intermediates and fine chemicals.

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the synthesis of active pharmaceutical ingredients (APIs), especially those requiring long-chain aliphatic segments with reactive termini.
• Agrochemical Synthesis: Used in the research and development of novel pesticides, herbicides, and plant growth regulators where its specific carbon chain length is advantageous.
• Fragrance & Flavor Chemistry: Acts as a precursor for musk-like compounds and other specialty aroma chemicals due to its undecene backbone.
• Material Science Research: Employed in the synthesis of monomers for specialty polymers, surfactants, and liquid crystals.
• Organic Synthesis Building Block: The dimethoxy acetal group provides a protected aldehyde, allowing for selective transformations at the alkene end, making it a versatile tool in multi-step syntheses.
• Cross-Coupling Reactions: The terminal alkene functionality makes it a suitable substrate for metathesis and other metal-catalyzed coupling reactions to build larger molecular architectures.
