2024-06-30


In the fields of modern biochemistry and medical diagnosis, the determination of hydrogen peroxide is of great significance. It not only serves as a product of various enzymatic reactions in organisms, but also participates in many physiological and pathological processes. Therefore, accurate and rapid determination of hydrogen peroxide concentration is crucial for diagnosis. In recent years, with the continuous progress of science and technology, enzymatic spectrophotometry has been widely used in the determination of hydrogen peroxide as a highly sensitive and easy to operate analytical method. HDAOS reagent(N - (2-hydroxy-3-sulfopropyl) -3 ', 5' - dimethoxyaniline sodium salt), as a novel colorimetric reagent, provides a new choice for enzymatic photometric determination of hydrogen peroxide.

Characteristics of HDAOS

 

HDAOS is a highly water-soluble aniline derivative with the following significant characteristics:

 

1. Strong stability: HDAOS exhibits good stability during storage and use, and is not easily oxidized or decomposed, ensuring the accuracy and reliability of measurement results.

 

2. High sensitivity: HDAOS has a fast reaction rate with hydrogen peroxide, high sensitivity, and can form a stable color reaction in a short period of time, improving the measurement efficiency.

 

3. Good selectivity: HDAOS has a high degree of selectivity towards hydrogen peroxide and can accurately determine the concentration of hydrogen peroxide in complex samples, avoiding interference from other substances.

 

Application of HDAOS in Enzymatic Photometric Determination of Hydrogen Peroxide

 

In the enzymatic determination of hydrogen peroxide, HDAOS is usually used in combination with compounds such as 4-aminoantipyrine (4-AA) or 3-methylbenzothiazolesulfone hydrazone (MBTH). These compounds can undergo oxidative coupling reactions with HDAOS in the presence of hydrogen peroxide and appropriate enzymes (such as horseradish peroxidase), producing highly stable purple or blue dyes. The color depth of this dye is directly proportional to the concentration of hydrogen peroxide in the sample, so the concentration of hydrogen peroxide can be indirectly determined by measuring the absorbance of the dye.

 

During the determination process, it is necessary to mix the sample to be tested with reagents containing horseradish peroxidase and HDAOS, and then add an appropriate amount of 4-AA or MBTH as the chromogenic agent. Under the action of enzymes, hydrogen peroxide reacts with HDAOS to form stable color products. Measure the absorbance of color products using a spectrophotometer and calculate the concentration of hydrogen peroxide in the sample based on the standard curve. The enzymatic spectrophotometry using HDAOS as a colorimetric reagent is easy to operate, does not require complex sample pretreatment steps, and reduces the cost of measurement and time.
