Description

Fluorescein Mercuric Acetate is a specialized organomercury compound that serves as a critical reagent in analytical chemistry and biochemical research. Its primary value lies in its unique ability to act as a selective fluorescent probe and labeling agent for thiol groups in proteins and other biomolecules. This makes it an essential tool for researchers and quality control laboratories in the pharmaceutical, biotechnology, and diagnostic sectors requiring precise molecular analysis and detection.

Application

• Biochemical Research & Protein Analysis: Used as a fluorescent label for the selective detection and quantification of cysteine residues and other thiol-containing compounds in proteins and peptides.
• Pharmaceutical Quality Control: Employed in assay development and impurity profiling for drug substances where thiol group interaction is a critical quality attribute.
• Diagnostic Reagent Manufacturing: Serves as a key component in the formulation of specific diagnostic kits and stains for clinical and research laboratories.
• Enzymology Studies: Utilized to probe the active sites of enzymes that contain critical cysteine residues, aiding in mechanistic studies.
• Material Science & Polymer Chemistry: Applied in surface modification and as a coupling agent for materials where thiol-mercury chemistry is applicable.

Quality Control

Our Fluorescein Mercuric Acetate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including purity assay by titration or HPLC, identification by FT-IR, and control of key impurities. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to ensure traceability and compliance with your research or production standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Keep away from incompatible materials such as strong acids, strong oxidizing agents, and other reactive chemicals. Due to its mercury content, handle with appropriate precautions and dispose of in accordance with all local, state, and federal regulations.
