Description

cis-Parinaric Acid Methyl Ester is a highly conjugated, naturally occurring fatty acid methyl ester valued for its unique spectroscopic properties. This compound serves as a crucial fluorescent probe and spectroscopic label in biophysical research due to its sensitivity to membrane lipid packing and phase transitions. It is primarily utilized by researchers and manufacturers in the life sciences, analytical chemistry, and advanced material development sectors for studying lipid bilayers, protein-lipid interactions, and oxidative processes.

Application

• Fluorescent Probe for Membrane Studies: Used to investigate lipid bilayer fluidity, phase transitions, and microdomain formation in model and biological membranes.
• Spectroscopic Marker for Lipid Oxidation: Acts as a sensitive intrinsic probe to monitor lipid peroxidation and oxidative stress in biological systems.
• Research Tool in Biophysics: Employed in fluorescence anisotropy, quenching, and resonance energy transfer (FRET) experiments to study molecular order and dynamics.
• Analytical Reference Standard: Serves as a high-purity standard for chromatography (HPLC, GC) and mass spectrometry in lipidomics and metabolomics research.
• Photochemical Studies: Utilized in research on photopolymerization and as a model compound for studying the behavior of conjugated polyenes.

Quality Control

Our cis-Parinaric Acid Methyl Ester is produced and handled under stringent quality protocols to ensure batch-to-batch consistency and high purity for research applications. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and stability parameters. We adhere to Good Manufacturing Practices (GMP) where applicable for laboratory chemicals, ensuring reliable performance in sensitive experimental settings.

Storage

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