Description

1-Stearoyl-3-Arachidoyl-Rac-Glycerol is a structured triacylglycerol (TAG) composed of stearic and arachidic acids esterified to a glycerol backbone. This specific molecular configuration is valued for its unique physical and nutritional properties, making it a critical component in advanced lipid research and formulation. It serves as a key intermediate and reference standard for scientists and manufacturers in the pharmaceutical, nutraceutical, and specialty chemical industries.

Application

• Pharmaceutical Excipient Development: Used as a lipid matrix for controlled-release drug delivery systems and solubility enhancement of poorly soluble active pharmaceutical ingredients (APIs).
• Nutritional Science & Structured Lipids: Acts as a model compound for studying fat metabolism and for designing structured lipids with specific nutritional or functional benefits.
• Biochemical Research: Serves as a high-purity substrate or standard in enzymatic studies, lipidomics research, and metabolic pathway analysis.
• Reference Standard: Essential for analytical method development, calibration, and quality control in laboratories quantifying complex lipid mixtures.
• Cosmetic & Personal Care Formulations: Utilized as an emollient and texture modifier in high-end skincare products for its specific melting profile and skin feel.
• Specialty Chemical Synthesis: Functions as a versatile building block for the synthesis of more complex lipids, surfactants, and bio-based polymers.

Quality Control

Our 1-Stearoyl-3-Arachidoyl-Rac-Glycerol is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chromatography (HPLC, GC) and spectroscopic methods, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided to guarantee the material meets your research or cGMP-grade requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere (e.g., nitrogen or argon) to minimize oxidation. For long-term storage, keep the container sealed in a cool, dry place. Allow the product to reach room temperature in a desiccator before opening to prevent moisture condensation.
