Description

Rac-3-Hydroxyoctadecanoic Acid is a chiral hydroxy fatty acid derivative of stearic acid. This compound serves as a valuable chemical intermediate and building block for synthesizing more complex molecules, including surfactants, lipids, and pharmaceutical agents. It is primarily utilized by research institutions, pharmaceutical developers, and specialty chemical manufacturers engaged in organic synthesis and material science.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon in the research and development of active pharmaceutical ingredients (APIs) and drug candidates.
• Biochemical Research: Used as a standard or substrate in enzymatic studies, lipid metabolism research, and the investigation of fatty acid oxidation pathways.
• Surfactant & Detergent Synthesis: Acts as a precursor for producing specialized surfactants and emulsifiers with potential applications in cosmetics and industrial cleaners.
• Material Science: Employed in the synthesis of polymers, coatings, and advanced materials where modified fatty acids impart specific physical properties.
• Reference Standard: Provides a high-purity standard for analytical methods, including chromatography (HPLC, GC) and spectrometry, in quality control laboratories.

Quality Control

Our Rac-3-Hydroxyoctadecanoic Acid is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specific results for purity, chiral composition, and impurities are available for every shipment upon request, supporting your regulatory and research needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent absorption of moisture from the atmosphere.
