2. Physical properties

Appearance: White or beige crystalline powder.

Odor: odorless, tasteless.

Melting point: 168-171 ° C.

Boiling point: 368.6 ± 37.0 ° C (at 760mmHg).

Density: 1.1 ± 0.1g/cm ³.

Flash point: 210.8 ± 26.0 ° C.

Solubility: Difficult to dissolve in water, easily soluble in organic solvents such as acetone, ether, dimethyl sulfoxide, dimethylformamide, etc.

3. Chemical properties

Stability: It is sensitive to moisture and light, and can maintain good chemical properties under extreme conditions such as high temperature and high pressure. It is a relatively stable organic compound.

Electrochemical performance: It exhibits high reversibility and stability in redox reactions, and the amino group (- NH ₂) in its molecular structure is prone to oxidation reactions, generating products with color changes.

Color reaction: As a substrate of peroxidase, its colorless aqueous solution will turn blue-green under the action of hydrogen peroxide or peroxidase, with a maximum absorption wavelength of around 655nm. The reaction product is stable, the color change is obvious, and it is easy to observe.

4. Purpose

Clinical laboratory testing: As a new substrate for peroxidase in clinical biochemical testing, it is widely used in enzyme immunoassay (EIA) and enzyme-linked immunosorbent assay (ELISA) to detect various biomarkers, such as hormones, tumor markers, pathogen antibodies, etc.

Forensic testing: In the field of forensic medicine, it can be used to detect traces such as blood stains and fingerprints. For example, in criminal investigation, the TMB manifestation rule is a commonly used method for displaying and extracting occult blood fingerprints.

Environmental monitoring: It can be used as a sensitive component of sensors to detect harmful substances in the environment, such as heavy metal ions, organic pollutants, etc. By reacting specifically with these substances, color changes or electrochemical signal changes can be produced, thereby achieving qualitative or quantitative analysis of pollutants.

Battery materials: They exhibit excellent electrochemical performance and stability in new types of batteries such as lithium-ion batteries and sodium ion batteries, and can be used as electrode materials or electrolyte additives to improve battery performance and lifespan.

5. Storage conditions: It should be stored at 2-8 ° C, dry, away from light, and kept away from metals.

6. Safety information: The hazard code is Xi, and the hazard level is 36/37/38. It may be irritating to the eyes, respiratory system, and skin. When using it, appropriate protective equipment such as gloves and goggles should be worn to avoid contact with the skin and eyes. Once in contact, rinse immediately with plenty of water.
