Description

1-Propanol, 2-Methoxy-3-(Octadecyloxy)-, (2S)- is a high-purity, stereochemically defined synthetic intermediate and specialty surfactant. This compound matters for its unique amphiphilic structure, combining a chiral glycerol-derived backbone with a long-chain alkyl ether, which imparts specific surface-active and self-assembly properties. It is needed by researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors for applications requiring precise molecular architecture, such as chiral synthesis, lipid nanoparticle formulation, and the development of non-ionic surfactants with tailored hydrophile-lipophile balance (HLB).

Application

• Pharmaceutical Intermediate: Used in the synthesis of chiral active pharmaceutical ingredients (APIs) and prodrugs, particularly those requiring lipid-like carriers.
• Lipid Excipient: Serves as a component in lipid-based drug delivery systems, including liposomes and solid lipid nanoparticles (SLNs) for enhanced bioavailability.
• Specialty Surfactant: Functions as a non-ionic surfactant or co-emulsifier in high-performance formulations for cosmetics, agrochemicals, and coatings.
• Chemical Research: A valuable building block in organic synthesis and materials science for creating novel amphiphilic polymers and liquid crystals.
• Analytical Standard: Employed as a reference standard in chromatographic analysis and quality control for related compound families.
