Description

Chlorophyll D is a specialized photosynthetic pigment, a key accessory chlorophyll found in certain cyanobacteria and marine algae. Its unique absorption profile in the far-red region of the light spectrum makes it a compound of significant scientific and commercial interest for advanced photobiology research. This high-purity material is essential for researchers and developers in the fields of photosynthesis studies, bio-inspired energy systems, and natural pigment applications.

Application

• Photosynthesis & Photobiology Research: A critical standard and reagent for studying far-red light absorption mechanisms and energy transfer in specialized photosynthetic organisms.
• Bio-inspired Solar Energy: Used in the development of novel, nature-inspired light-harvesting complexes and artificial photosynthetic systems for renewable energy applications.
• Natural Pigment & Colorant Studies: Serves as a reference compound for the analysis and characterization of complex chlorophyll mixtures in environmental and food science.
• Phycology & Marine Biology: Essential for identifying and studying cyanobacteria (e.g., *Acaryochloris marina*) and algae that utilize Chlorophyll D as a primary pigment.
• Spectroscopic Calibration: Acts as a calibration standard for UV-Vis, fluorescence, and other spectroscopic instruments due to its distinct spectral signature.
• Educational & Reference Standards: Supplied to academic and industrial laboratories as a high-purity chemical standard for analytical and teaching purposes.

Quality Control

Our Chlorophyll D is produced and handled under strict quality protocols to ensure batch-to-batch consistency and high purity, suitable for demanding research applications. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and relevant spectroscopic data. We adhere to Good Manufacturing Practice (GMP) principles for laboratory chemicals to guarantee traceability and reliability for our global clientele.

Storage

Preserve in a tightly closed container, protected from light. Store under inert atmosphere (e.g., nitrogen or argon) at -20°C or below for long-term stability. For short-term use, store at 2-8°C. The material is light-sensitive and should be handled under subdued light or in amber glass vials to prevent degradation.
