Description

Plastoquinol CAS NO 3819-09-8 is a reduced, hydroquinone form of plastoquinone, a critical component of the photosynthetic electron transport chain in plants and cyanobacteria. This compound serves as a vital electron carrier and antioxidant within Photosystem II, making it essential for research into photosynthesis, oxidative stress, and plant biochemistry. It is primarily utilized by researchers and manufacturers in the life sciences, agricultural chemistry, and nutraceutical sectors for biochemical studies, enzyme assays, and as a reference standard.

Application

• Biochemical Research: Critical reagent for studying the mechanism of photosynthesis, specifically electron transfer within Photosystem II.
• Enzyme Activity Assays: Used as a substrate or cofactor in assays for enzymes like plastoquinol-plastocyanin reductase.
• Reference Standard: Serves as a high-purity analytical standard for HPLC, LC-MS, or NMR to quantify plastoquinone/plastoquinol levels in biological samples.
• Antioxidant Studies: Investigated for its role in mitigating reactive oxygen species (ROS) within chloroplasts and related antioxidant mechanisms.
• Plant Physiology & Agriculture: Research into plant stress responses, herbicide mode of action, and crop yield optimization.
• Nutraceutical & Cosmetic R&D: Exploration of potential antioxidant benefits in human health and skincare formulations.

Quality Control

Our Plastoquinol is produced and handled under strict quality protocols to ensure batch-to-batch consistency and high purity for research applications. Quality is verified through advanced analytical techniques including HPLC, NMR, and mass spectrometry. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your regulatory and research documentation needs.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) to prevent oxidation. Allow the container to reach room temperature in a desiccator before opening to minimize moisture uptake and thermal stress.
