Description

Chlorophyll A' CAS NO 22309-13-3 is a specific derivative of chlorophyll, the essential green pigment responsible for photosynthesis in plants and cyanobacteria. This high-purity compound is critical for research and industrial applications requiring a defined chlorophyll standard. It serves as a vital analytical reference material and a key ingredient for manufacturers in the nutraceutical, food colorant, and cosmetic industries seeking natural, plant-based pigments.

Application

• Analytical Reference Standard: Used for calibration, identification, and quantification in HPLC, spectrophotometry, and other analytical methods in environmental and food testing laboratories.
• Nutraceutical & Dietary Supplements: Incorporated as an active ingredient in chlorophyllin-based supplements for its purported antioxidant and detoxification properties.
• Natural Food Colorant: Provides a stable green color in food and beverage products, appealing to the clean-label market.
• Cosmetics & Personal Care: Used in formulations such as creams, lotions, and soaps for its natural coloring and potential skin-beneficial properties.
• Photosynthesis & Plant Physiology Research: Essential for studying light absorption, energy transfer mechanisms, and photosynthetic efficiency in academic and agricultural research.
• Pharmaceutical Intermediates: Serves as a starting material or precursor for the synthesis of more complex chlorophyll-derived compounds with potential therapeutic applications.
