Description

Leucopelargonidin CAS NO 520-17-2 is a colorless flavan-3,4-diol, a key member of the proanthocyanidin class of natural polyphenols. This compound serves as a fundamental building block and precursor in the biosynthesis of condensed tannins, making it a critical reference standard and research chemical. It is essential for researchers and manufacturers in the nutraceutical, cosmetic, and pharmaceutical industries who are developing products focused on antioxidant activity, vascular health, and natural color stabilization.

Application

• Pharmaceutical Research: Used as a high-purity reference standard in analytical methods (HPLC, LC-MS) for quantifying proanthocyanidins in botanical extracts and biological samples.
• Nutraceutical Development: Serves as a key intermediate and marker compound in the research and quality control of dietary supplements targeting antioxidant support and cardiovascular health.
• Cosmetic Science: Investigated for its potential antioxidant and skin-protective properties in formulations for anti-aging and UV-protection serums and creams.
• Food & Beverage Analysis: Employed as an analytical standard to study the proanthocyanidin content, astringency, and color stability in foods like fruits, berries, wines, and teas.
• Biochemical Studies: Fundamental for in-vitro and in-vivo research on the metabolism, bioavailability, and biological activities of flavanols and their oligomers.
• Plant Chemistry & Agriculture: Used in studies of plant defense mechanisms, pigmentation, and the nutritional quality of crops.
