Description

1,2-Distearoyl-Sn-Glycerol is a high-purity synthetic diglyceride, specifically the 1,2-isomer of distearoylglycerol. This compound serves as a critical intermediate and building block in the synthesis of complex lipids, phospholipids, and other specialty chemicals. It is essential for researchers and manufacturers in the pharmaceutical, cosmetic, and advanced material science industries who require precise and well-defined lipid structures for product development and formulation.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of phospholipids (e.g., phosphatidylcholine) for liposomal drug delivery systems and other nanomedicines.
• Biochemical Research: Used as a standard or substrate in enzymatic studies, lipid metabolism research, and membrane biophysics.
• Cosmetic Ingredient Synthesis: Employed in the production of emulsifiers, stabilizers, and conditioning agents for high-end skincare and haircare formulations.
• Specialty Surfactants: Acts as a raw material for manufacturing non-ionic surfactants with specific hydrophilic-lipophilic balance (HLB) properties.
• Food-Grade Additive Production: A starting material for synthesizing food emulsifiers like polyglycerol polyricinoleate (PGPR) after further chemical modification.
• Material Science: Used in the development of biodegradable polymers, gels, and lipid-based coatings.
