There are various new Trinder’s color reagents, why choose MAOS?,CAS82692-97-5,C13H22NNaO5S,
New Trinder's color reagent MAOS, also called N-ethyl-N-(2-hydroxy-3-sulfopropyl)-3,5-dimethylaniline sodium salt monohydrate, its CAS number is 82692-97- 5. Like other new Trinder's reagents, its water solubility is high and the sensitivity is much higher than the traditional color reagents commonly used in laboratories. MAOS test strips are actually used to determine analytes and their use methods, so they are widely used in clinical testing and biochemical reagents In the box. There are ten kinds of new Trinder’s color reagents: ADPS, TOOS, TOPS, MAOS, MADB, etc. So what is special about MAOS compared with other color reagents?
It can be seen from the table below that the molar absorbance of ALPS, TOOS, TODB, TOPS is higher, which means that the sensitivity of the color reaction is higher, and it can be used for the determination of very small amounts of test items in the serum. The absorption wavelength of MAOS is relatively high. When γmax=630nm and pH=5.5~9.5, it is less interfered by other substances in the serum, which can be used for detection items that require high precision values.
Firstly, the biggest characteristic of MAOS is that the maximum absorption wavelength of its oxidized product is far more than that of common color reagents. Even in the new Trinder's reagent, the ultraviolet absorption wavelength of its product is 630 nm, which is quite high.The maximum absorption wavelength of products of many chromogenic reagents is in the visible region. If it is used to detect human blood or other body fluids, due to the complexity of the components in the sample to be tested, the sample itself contains a small amount of components whose absorption wavelength is in the visible region or similar to the absorption wavelength of the chromogenic products, which will make the detection results higher.If, like MAOS, the maximum absorption wavelength of the product is in the ultraviolet region and is relatively high, the interference will be greatly reduced.Therefore, MAOS is recommended as a chromogenic substrate for some biochemical detection items requiring highly accurate values.
Secondly, the color reaction of MAOS chromogenic substrate has a wide range of adaptability to the pH of the reaction system, which greatly improves its adaptability.Some chromogenic reagents often react under acidic conditions, but the participation of enzymes is usually required in biochemical detection. We know that the catalytic action of enzymes is relatively sensitive to the pH of the reaction environment, and can not match with the chromogenic reagents or even inactivate them, which will be greatly limited in use, while MAOS reagents do not have this problem.
In addition, the molar absorbance of MAOS color reaction is relatively high, so its sensitivity is also relatively high.It should be noted that MAOS will fade when the detection time is too long, so MAOS detection needs to be completed in time and can not be interrupted.In addition, MAOS is also relatively safe, unlike biphenyl reagents such as DAB, although the price is relatively low, it has certain carcinogenicity or mutagenicity.
