Description

Dioleoylthioglycerol is a specialized organosulfur compound derived from glycerol, featuring two oleoyl chains linked via a thioester bond. This unique structure makes it a valuable intermediate and functional additive, particularly in applications requiring lipid conjugation or as a precursor for synthesizing more complex amphiphilic molecules. It is primarily utilized by researchers and manufacturers in the pharmaceutical, cosmetic, and specialty chemical industries. Dioleoylthioglycerol CAS NO 91860-74-1 is known for its role in advanced formulation development.

Application

• Pharmaceutical Research & Development: Used as a key intermediate in the synthesis of prodrugs, lipid-based drug delivery systems (e.g., liposomes, solid lipid nanoparticles), and bioactive conjugates.
• Cosmetic & Personal Care Formulations: Acts as a skin-conditioning agent, emulsifier, or a precursor for custom esters in high-performance creams, lotions, and serums.
• Biochemical Research: Serves as a substrate or building block for studying enzyme activity (e.g., lipases, esterases) and for constructing model membranes or lipid anchors.
• Specialty Surfactants & Lubricants: Employed in the development of niche surfactants, lubricant additives, and release agents due to its oleochemical backbone.
• Polymer & Material Science: Utilized as a monomer or modifier in the synthesis of biodegradable polymers, resins, and functional materials.

Quality Control

Our Dioleoylthioglycerol is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chromatographic purity assessment and identity confirmation, to ensure it meets precise customer specifications and consistent high-quality standards. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C or as specified on the label or COA. This product is easily oxidized and light-sensitive. Keep away from strong oxidizing agents, heat, and ignition sources. Allow the sealed container to reach ambient temperature before opening to prevent moisture condensation.
