Description

Chlorophyll A, Divinyl-(Sh) is a specific chlorophyll derivative characterized by the presence of divinyl groups at the C-3 and C-8 positions, which distinguishes it from the more common monovinyl forms. This structural feature is of significant interest in research fields such as photosynthesis studies and plant physiology, as it can influence light absorption and energy transfer properties. It serves as a valuable analytical standard and research chemical for scientists in phytoplankton research, marine biology, and the development of advanced photosynthetic models.

Application

• Phytoplankton Research & Oceanography: Used as a specific biomarker and analytical standard for identifying and quantifying divinyl chlorophyll-containing phytoplankton, such as *Prochlorococcus*, in marine ecosystems.
• Photosynthesis Studies: Employed in biochemical research to investigate the structure-function relationship of chlorophylls, energy transfer mechanisms, and photosynthetic efficiency in various organisms.
• Analytical Reference Standard: Serves as a high-purity certified reference material (CRM) for the calibration of HPLC, LC-MS, and spectrophotometric instruments in environmental and biological testing laboratories.
• Plant Physiology & Stress Response: Utilized in studies examining chlorophyll biosynthesis pathways and how environmental factors affect pigment composition in plants and algae.
• Educational & Diagnostic Kits: Incorporated into advanced educational kits and diagnostic assays for teaching and researching photosynthetic pigments.

Quality Control

Our Chlorophyll A, Divinyl-(Sh) is produced and handled under controlled conditions to ensure research-grade integrity and batch-to-batch consistency. Each lot undergoes comprehensive analysis via HPLC and spectrophotometric methods to verify identity and purity. A detailed Certificate of Analysis (COA) documenting exact specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below under an inert atmosphere. The product is light-sensitive and should be handled under subdued light conditions to prevent degradation. Allow the sealed vial to reach room temperature before opening to minimize moisture condensation.
