Description

1-Undecene is a versatile, high-purity linear alpha olefin (LAO) with the CAS number 821-95-4, serving as a critical building block in advanced organic synthesis and specialty chemical manufacturing. Its terminal double bond makes it a highly reactive intermediate for creating a wide range of functional derivatives, from surfactants to fine chemicals. This product is essential for R&D laboratories, flavor & fragrance houses, and industrial manufacturers seeking a reliable, high-quality C11 feedstock.

Application

• Organic Synthesis Intermediate: A key starting material for the production of specialty chemicals, including alcohols, aldehydes, acids, and amines via hydroformylation, oxidation, or amination reactions.
• Flavor and Fragrance Industry: Used in the synthesis of aroma chemicals and musk intermediates, contributing to complex scent profiles in perfumes and consumer products.
• Surfactant and Detergent Manufacturing: Acts as a precursor for the synthesis of biodegradable surfactants and detergent alcohols, particularly for niche applications requiring specific carbon chain lengths.
• Polymer and Plasticizer Production: Employed as a comonomer in the production of linear low-density polyethylene (LLDPE) and in the synthesis of specialized plasticizers and lubricant additives.
• Pharmaceutical and Agrochemical Intermediates: Serves as a building block in the synthesis of active pharmaceutical ingredients (APIs) and crop protection agents.
• Research & Development: A valuable reagent in academic and industrial R&D for studying olefin chemistry, catalysis, and material science.
