Description

cis-Parinaric Acid CAS NO 593-38-4 is a naturally occurring, conjugated polyunsaturated fatty acid widely recognized as a sensitive fluorescent probe for studying membrane fluidity and lipid peroxidation. Its unique structure allows it to incorporate into lipid bilayers, making it an essential tool for biophysical and biochemical research. This high-purity compound is primarily utilized by researchers and manufacturers in the life sciences, pharmaceutical development, and advanced material sectors.

Application

• Biophysical Research Probe: As a fluorescent marker for monitoring membrane fluidity, phase transitions, and lipid packing in model and biological membranes.
• Lipid Peroxidation Studies: Used to detect and quantify free radical damage and oxidative stress in lipid systems due to its sensitivity to oxidation.
• Pharmaceutical Development: Employed in formulation studies to understand drug-lipid interactions and the stability of liposomal drug delivery systems.
• Biochemical Assays: Serves as a substrate in enzymatic studies related to lipid metabolism and antioxidant activity.
• Material Science: Investigation of lipid-based polymers and the physicochemical properties of advanced lipid materials.

Quality Control

Our cis-Parinaric Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and development. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Due to its properties of being easily oxidized (store under inert atmosphere) and strictly light-sensitive (protect from all light exposure), it is recommended to store the product under an inert gas (e.g., argon or nitrogen) at -20°C or below. Allow the sealed container to reach room temperature before opening to minimize moisture condensation.
