Description

Spirilloxanthin is a naturally occurring C40 carotenoid pigment belonging to the xanthophyll class, characterized by its distinctive purple-red color. This compound matters for its potent antioxidant properties and its role as a valuable biochemical marker and research standard. It is primarily needed by manufacturers and researchers in the nutraceutical, cosmetic, and life science industries seeking high-purity natural pigments and analytical reference materials.

Application

• Nutraceutical & Dietary Supplement Formulation: Utilized as a natural antioxidant ingredient and a source of provitamin A activity.
• Cosmetic & Personal Care Products: Incorporated into formulations for its coloring properties and potential skin-protective benefits against oxidative stress.
• Biochemical & Microbiological Research: Serves as a critical standard and reagent in studies of carotenoid biosynthesis, particularly in photosynthetic bacteria like *Rhodospirillum rubrum*.
• Food Coloring Agent (where approved): Potential use as a natural colorant for food products, subject to regional regulatory compliance.
• Analytical Reference Standard: High-purity grade is essential for HPLC, LC-MS, and other analytical methods for quantification and identification in complex matrices.
• Photoprotective Studies: Investigated for its role in photoprotection and light-harvesting in bacterial photosynthesis models.

Quality Control

Our Spirilloxanthin is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, UV-Vis), to ensure it meets the stringent requirements for research and industrial applications. Certificates of Analysis (COA) detailing batch-specific results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C or as indicated on the label or COA. This product is easily oxidized and light-sensitive; prolonged exposure to air, light, or elevated temperatures should be avoided to maintain stability and purity.
