TOOS CAS NO.82692-93-1
TOOS, full name N-ethyl-N-(2-hydroxy-3-sulfopropyl)-3-methylaniline sodium salt, a widely used chromogenic reagents, among the new Trinder's reagents, are most commonly used. TOOS is used in many clinical biochemical testing projects.
The TOOS chemical produced by Desheng is a white crystalline powder with CAS number 82692 93 1. In the field of in vitro diagnosis, it is mainly used for the detection of blood glucose metabolism series items, such as the preparation of glucose detection kits, glycated albumin detection kits, serum uric acid detection kits, etc.
TOOS Product Advantages
In terms of the fading of the color product, the absorbance of the color reaction product formed by TOOS does not change much with time, that is, the color reaction product is stable and not easy to fade.
TOOS has good performance in absorption wavelength, color reaction intensity and fading, so TOOS is the most commonly used.
TOOS has a high molar absorbance, and can be used for the determination of very small amounts of the test items in serum. If the test items are in the 550nm~600nm range, and their content is extremely small, then MAOS and MADB need to be used.
The chromogen substrate TOOS produced by Desheng has the characteristics of high purity, good water solubility and small batch-to-batch variation;
The TOOS chemical produced by Desheng has the characteristics of less interfering impurity ions. It is very convenient to use when it is used.
Desheng TOOS products are pure white crystalline powder with uniform shape and good performance in color reaction intensity and fading;
Desheng has a professional foreign trade team, rich export experience, and can deal with various problems in transportation in a timely manner.
Precautions for Use of TOOS
As a chromogen substrate product with reducing properties TOOS, although it is configured in the form of a solution during use, there will still be slow oxidation in the air, so in general, it is recommended to prepare and use now, and it is necessary to add a certain amount of excessive Catalyzed by oxidase, the chromogen substrates produced by Desheng are basically pure white crystalline powders, which will not be affected in a sealed environment, but will be slowly oxidized and discolored when exposed to air for a long time.
What Testing Items Can TOOS Be Used For?
The chromogen substrate TOOS can be used in a variety of diagnostic reagents, such as blood sugar testing, routine liver function tests, blood lipid testing items such as triglycerides, and cholesterol testing items, and for different biochemical tests, the concentration used will be different. The concentration of TOOS chemical is basically around 1~5mmol/L under the state. TOOS raw material not only has the characteristics of high sensitivity and stability, but also has good performance in color reaction intensity and fading, which is of great value in clinical diagnosis.
Preservation of Chromogen Substrate TOOS
The premise that TOOS can produce a color reaction is that it cannot be oxidized in advance during storage, otherwise it may cause a low detection result. Taking Desheng's TOOS reagent as an example, the finished products are all in the form of solid powder, which is stored in a seal at low temperature, so that TOOS powder will not be slowly oxidized by air due to long-term storage, nor will it deteriorate due to excessive temperature or exposure to light. Also prevent storage with oxides and acids.
