Description

All cis-7,10,13,16,19-Docosapentaenoic Acid Ethyl Ester is a high-purity ethyl ester derivative of the ω-3 fatty acid DPA (docosapentaenoic acid, n-3). This specialized chemical intermediate is critical for research and development in advanced nutrition and pharmaceutical synthesis, offering a defined and concentrated form of the bioactive DPA molecule. It is primarily utilized by manufacturers in the nutraceutical, pharmaceutical, and life science research sectors for formulating high-value products and conducting metabolic studies.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs targeting inflammatory and metabolic pathways.
• Nutraceutical Formulation: Serves as a key ingredient in high-potency dietary supplements and functional foods focused on cardiovascular and cognitive health.
• Biochemical Research: Acts as a standard and reagent in lipidomics research, cell culture studies, and investigations into ω-3 metabolism and signaling.
• Reference Standard: Employed as a certified reference material (CRM) for analytical method development and quality control in laboratories.
• Cosmeceutical Applications: Incorporated into advanced skincare formulations for its potential anti-inflammatory and skin-barrier supporting properties.

Quality Control

Our All cis-7,10,13,16,19-Docosapentaenoic Acid Ethyl Ester is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure identity, purity, and conformity to specifications. Certificates of Analysis (COA) with detailed chromatographic data are provided to guarantee traceability and batch-to-batch consistency for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation. Allow the container to reach room temperature before opening to minimize moisture condensation. Keep away from heat and oxidizing agents.
