TOPS Trinder Reagent Cas 40567-80-4 N-Ethyl-N-(3-Sulfopropyl)-3-Methylaniline Sodium Salt

TOPS Trinder Reagent Cas 40567-80-4 N-Ethyl-N-(3-Sulfopropyl)-3-Methylaniline Sodium

The full name of TOPS is N-ethyl-N-(3-sulfopropyl)-3-methylaniline sodium salt, which is one of the new Trinder's color reagents, CAS number is 40567-80-4, and the appearance is white crystalline powder . Because of its molecular structure and the sulfopropyl group on the single atom connected to the benzene ring, there is one less hydroxyl group, which has a slightly stronger stability, high water solubility, and high detection sensitivity. It is widely used in diagnostic testing and biochemical testing, mainly for the colorimetric determination of uric acid and cholesterol; when used as a water-soluble reagent, it can be used to determine hydrogen peroxide by enzymatic photometry.

As a new technology enterprise, Desheng produces more than a dozen Trinder’s reagents, such as TOOS, MAOS, TOPS, ADOS, ADPS, ALPS, DAOS, HDAOS, MADB, etc., which are not only water-soluble, but no difference in approvals. Whether it is impeccable in terms of purity, sensitivity, stability or appearance, the quality inspection department strictly controls all the links of the color reagent raw materials from storage to production, which also provides a solid guarantee for the products. So where are the specific advantages of TOPS?

Oxidation reaction

Use

It can be used as a water-soluble reagent for the determination of hydrogen peroxide by enzymatic spectrophotometry. It is widely used in diagnostic detection and biochemical tests.

Advantage

The purity (> 99%) is water-soluble, the process is stable, and the appearance of the product can be guaranteed to be pure white crystal powder.

In the presence of hydrogen peroxide and peroxidase, the top reagent forms very stable purple or blue dye in the oxidation coupling reaction with 4-aminoantipyrine (4-AA) or 3-methylbenzothiazolylsulfonhydrazone (MBTH). The substrate is oxidised by its oxidase to produce hydrogen peroxide.

The concentration of hydrogen peroxide corresponds to the substrate concentration. Therefore, the amount of substrate can be determined by the color development of oxidation coupling reaction, and the relatively accurate test results of the concentration of the substance to be measured can be obtained.

Three advantages of Desun products TOPS:

1. Desheng has always been adhering to the company culture of virtue-oriented, honesty first, quality first, and leading technology. It specializes in the research and development, production and sales of blood collection tube additives, in vitro diagnostic reagents, buffers, and luminescent substrates. And there is a dedicated research and development department, so Desheng products are supplied by TOPS manufacturers, and the price is favorable and the price difference is not earned.

2. Desheng products are ready-to-use and can be packaged according to customer needs. And the sub-assembly process is strict, and it is carried out in a professional sub-assembly table. The sub-assembly table is kept clean. The sub-packaging personnel must wear disposable gloves for sub-packaging. The clothing requirements of the staff are even stricter.

3. Desheng delivers fast. Orders are delivered on the same day (before four o'clock). The staff has a customer-oriented philosophy. Once the company had a customer with a very large order but the packaging was cumbersome. The company guaranteed that the customer’s order was on time Delivery, all staff help to sub-package, to ensure the delivery of the product.
