Description

Pyropheophytin A is a chlorophyll derivative formed during the processing and storage of plant materials. This compound matters as a key analytical marker for assessing food quality, authenticity, and processing history, particularly in the olive oil and green tea industries. It is needed by analytical laboratories, food quality control departments, and research institutions focused on phytochemistry and natural product analysis.

Application

• Food Quality & Authenticity Testing: Used as a critical marker in HPLC analysis to verify the authenticity, freshness, and processing conditions of olive oil and other plant-based oils.
• Tea Research & Grading: Serves as an important indicator in the study of tea leaf processing (e.g., green tea), where its concentration correlates with heat treatment and storage duration.
• Phytochemical Reference Standard: Employed as a high-purity analytical standard in laboratories for the quantification of chlorophyll degradation products in various plant extracts.
• Photosynthesis & Plant Physiology Studies: Utilized in research to understand chlorophyll metabolism, degradation pathways, and plant stress responses.
• Nutraceutical & Cosmetic Ingredient Analysis: Acts as a marker compound in the quality control of chlorophyll-rich supplements and natural colorants to ensure proper processing and stability.

Quality Control

Our Pyropheophytin A is produced and handled under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation (IR, UV-Vis), to ensure it meets the high standards required for analytical and research applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and chromatographic data is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C or as specified on the label or COA. The material is light-sensitive and easily oxidized; prolonged exposure to air, light, or elevated temperatures should be avoided to maintain stability and purity.
