2-(Undecyloxy)ethanol

2-(Undecyloxy)ethanol (CAS 38471-47-5) is a versatile amphiphilic building block engineered for surfactant synthesis, cosmetic formulation, and agrochemical emulsification . This molecule integrates a hydrophobic undecyl (C₁₁) alkyl chain with a hydrophilic 2-hydroxyethoxy terminus, creating a balanced amphiphilic architecture that enables surface activity, miscibility modulation, and phase-transfer capabilities . The terminal primary alcohol serves as a versatile handle for further derivatization—esterification, ethoxylation, or oxidation—while the ether linkage provides enhanced hydrolytic stability compared to ester-based surfactants . This intermediate is particularly valuable for constructing nonionic surfactants via ethoxylation, penetration enhancers for topical drug delivery, and solubilizing excipients where the C₁₁ chain length offers an optimal balance between lipophilicity and aqueous compatibility . Additionally, the compound functions as a male-produced aggregation pheromone (monochamol) for Monochamus beetle species, supporting pest management strategies in forestry applications . Manufactured with purity ≥95-98% under controlled conditions, it supports formulation development programs requiring tunable HLB values and stable glycol ether scaffolds.
