Description

Pheophytin A CAS NO 603-17-8 is a chlorophyll derivative formed by the removal of the central magnesium ion, serving as a key intermediate in chlorophyll metabolism and a natural green pigment. This compound is valued for its role as a reference standard in analytical chemistry and as a starting material for the synthesis of chlorophyll-related compounds. It is primarily sought by manufacturers and research institutions in the pharmaceutical, nutraceutical, and analytical reagent sectors for quality control, method development, and biochemical research.

Application

• Analytical Reference Standard: Used in HPLC and spectrophotometric methods for the identification and quantification of chlorophyll and its degradation products in plant extracts, food, and supplements.
• Pharmaceutical Research: Employed as a biochemical tool in studies investigating photosynthesis, photodynamic therapy, and antioxidant mechanisms.
• Nutraceutical Ingredient Analysis: Acts as a critical marker for standardizing and authenticating chlorophyll-rich products like spirulina, chlorella, and green food powders.
• Food Science: Utilized in research on food color stability, processing effects on green vegetables, and the development of natural colorants.
• Cosmetic Research: Investigated for potential applications in natural coloring agents and topical formulations due to its plant-derived origin.
• Teaching & Laboratory Reagent: Serves as a purified compound for educational demonstrations and advanced laboratory experiments in organic chemistry and botany.
