Description

Peridinin CAS NO 33281-81-1 is a naturally occurring carotenoid pigment, specifically a xanthophyll, found in dinoflagellates and other marine organisms. This compound is of significant commercial and research interest due to its unique light-harvesting and photoprotective properties. It is primarily sought after by manufacturers and researchers in the nutraceutical, cosmeceutical, and life science sectors for its potent antioxidant activity and role in specialized pigment-protein complexes.

Application

• Nutraceutical Formulations: Used as a high-value antioxidant ingredient in dietary supplements for its potential health benefits.
• Cosmeceutical Products: Incorporated into anti-aging and skin-protective creams and serums for its photoprotective and antioxidant effects.
• Biochemical Research: Serves as a critical reagent in photosynthesis studies, particularly for investigating light-harvesting complex II (LHCII) in marine algae.
• Natural Food Colorant: Potential application as a natural pigment in specialized food products, subject to regulatory approval.
• Reference Standard: Used as an analytical standard in HPLC and LC-MS for the quantification of carotenoids in biological and commercial samples.
• Aquaculture Feed Additive: Studied for its role in enhancing the coloration and health of farmed aquatic species.

Quality Control

Our Peridinin is produced and tested under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced chromatographic techniques, with key parameters including identity confirmation and potency assay. A Certificate of Analysis (COA) detailing purity, related substances, and other critical specifications is provided with every shipment to support your quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at -20°C or below for long-term stability. For short-term use, store at 2-8°C. The material is light-sensitive and easily oxidized; avoid exposure to air, heat, and light during handling.
