Description

7,8,11,12-Tetrahydro-ψ,ψ-Carotene is a partially hydrogenated derivative of the carotenoid family, specifically a tetrahydro form of psi,psi-carotene. This compound is valued for its role as a key intermediate in the synthesis of complex carotenoids and as a reference standard for analytical research. It is primarily sought by manufacturers and researchers in the nutraceutical, cosmetic, and fine chemical synthesis sectors who require high-purity, well-characterized biochemical intermediates.

Application

• Pharmaceutical & Nutraceutical Intermediate: Serves as a crucial building block in the synthesis of more complex carotenoids and vitamin A analogs for dietary supplements.
• Analytical Reference Standard: Used in high-performance liquid chromatography (HPLC) and mass spectrometry for the identification and quantification of carotenoids in various matrices.
• Cosmetic Ingredient Research: Investigated for potential antioxidant properties and as a precursor for colorants in cosmetic formulations.
• Biochemical Research: Employed in studies of carotenoid metabolism, absorption, and biological activity.
• Food Science: Used as a standard in the analysis of natural food colorants and the study of carotenoid degradation pathways.

Quality Control

Our 7,8,11,12-Tetrahydro-ψ,ψ-Carotene is produced under strict quality management protocols. Each batch is analyzed to ensure high chemical purity and identity, with testing typically including HPLC for assay and related substances. A comprehensive Certificate of Analysis (COA) detailing purity, physical characteristics, and test results is provided with every shipment to ensure traceability and compliance with your research or manufacturing standards.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C. The material is easily oxidized and light-sensitive; prolonged exposure to air, light, or elevated temperatures should be avoided to prevent degradation.
