Description

Retinal CAS NO 116-31-4 is the aldehyde form of Vitamin A, a critical chromophore essential for vision. This compound is fundamental to the visual cycle, where it binds to opsin proteins to form light-sensitive photoreceptors. It is a vital biochemical intermediate for research and development in the life sciences, pharmaceuticals, and nutraceutical industries.

Application

• Biochemical Research: Key reagent in studies of the visual cycle, phototransduction, and retinal metabolism.
• Pharmaceutical Synthesis: A crucial precursor in the production of retinoid-based drugs and therapies.
• Nutraceutical Formulation: Used in advanced vitamin A supplements and functional food products.
• Cell Culture & Diagnostics: Employed in specialized cell media and diagnostic assay development.
• Cosmeceutical R&D: Investigated for its role in skin health and anti-aging formulations.
• Reference Standard: Serves as a high-purity analytical standard for quality control in related industries.
