Description

Flavin Mononucleotide Semiquinone is a crucial intermediate redox state of the essential coenzyme Flavin Mononucleotide (FMN). This semiquinone radical form is of significant interest in biochemical research and industrial biocatalysis due to its unique electron transfer properties. It is primarily utilized by research institutions, pharmaceutical developers, and manufacturers of diagnostic reagents and enzyme-based processes who require a deep understanding of flavoprotein mechanisms.

Application

• Biochemical Research: Critical for studying electron transfer mechanisms in flavoproteins, enzyme kinetics, and redox biology.
• Pharmaceutical Development: Used as a reference standard and intermediate in the research of drugs targeting metabolic pathways and oxidative stress.
• Diagnostic Reagents: Serves as a key component in the formulation of advanced enzymatic assays and biosensors.
• Industrial Biocatalysis: Employed in the study and optimization of flavin-dependent enzymes used in fine chemical synthesis and bioremediation.
• Nutraceutical Research: Investigated for its potential role and stability in advanced riboflavin (Vitamin B2) formulations and delivery systems.

Quality Control

Our Flavin Mononucleotide Semiquinone is produced and handled under strict quality protocols to ensure batch-to-batch consistency and reliability for research and development purposes. Each lot is characterized using advanced analytical techniques to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing specific test results is provided with every shipment to support your quality assurance requirements.

Storage

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