Applications of 64285-73-0
| Industry | Application | Process |
|---|---|---|
| In Vitro Diagnostics | Chromogenic detection of peroxidase and hydrogen peroxide in urine and blood, for pregnancy tests, fecal occult blood tests, etc. | Oxidation reaction with hydrogen peroxide under peroxidase catalysis, generating a soluble blue quinone-type product for quantitative colorimetric analysis |
| Environmental Monitoring | Detection of hydrogen peroxide, peroxides, and certain heavy metal ions (e.g., copper, iron) in water | Colorimetric reaction of TMB catalyzed by specific oxidants or metal ions, applied in spectrophotometric determination |
| Biomedical Research | Substrate for horseradish peroxidase (HRP) in ELISA, immunohistochemistry, and Western blotting | HRP-catalyzed reaction of TMB hydrochloride with H₂O₂ yields a soluble blue product; acid termination converts it to yellow for absorbance measurement at 450 nm |
| Food Safety Testing | Rapid screening of peroxide value, residual hydrogen peroxide, and microorganisms (e.g., peroxidase-positive bacteria) in food | Colorimetric reaction using the TMB–H₂O₂–HRP system, implemented via lateral flow strips or microplate assays for semi-quantitative or quantitative analysis |
