Description

5,5-Dimethyl-β-Carotene is a synthetic, symmetrically substituted derivative of β-carotene, a prominent member of the carotenoid family. This modification enhances its stability and alters its spectral properties, making it a valuable analytical standard and research chemical for studying carotenoid chemistry and metabolism. It is primarily utilized by research institutions, analytical laboratories, and manufacturers in the nutraceutical and food science sectors who require high-purity reference materials for method development, quality control, and biochemical studies.

Application

• Analytical Reference Standard: Primary use as a high-purity standard for HPLC, LC-MS, and UV-Vis analysis in quality control laboratories.
• Biochemical Research: Investigation of carotenoid biosynthesis pathways, antioxidant mechanisms, and structure-activity relationships.
• Nutraceutical R&D: Used in the development and testing of fortified foods, dietary supplements, and functional ingredients.
• Photochemical Studies: Serves as a model compound for studying light absorption, isomerization, and degradation kinetics of carotenoids.
• Teaching & Education: A valuable compound for academic instruction in organic chemistry and natural product chemistry courses.
