The color reagent TOPS with excellent quality and price is here

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?

1. TOPS produced by Desheng, purity ≥98%(T), moisture content ≤5%, iron content <5PPM, pH range 6-8, ignition residue ≤0.1%, test water solubility is 500mg/ml water, Produce in strict accordance with industry standards;
2. Compared with other manufacturers, the price has an absolute advantage (inquire for details), the stock is sufficient, the output is large, and the shipment is fast, which can meet the customer's demand for products in time;
3. Good after-sales service, actively solve various problems encountered in the transaction process, ensure that the interests of customers are not lost, and truly satisfy customers and achieve the purpose of cooperation.
We have to do the following in TOPS storage:
1. Its water solubility predestined that it must be operated in a closed environment and in a dehumidified environment, otherwise it is easy to absorb moisture and cause its chemical properties to change.
2. Pack the product in a light-proof bottle because it is sensitive to light.
3. The temperature should be kept at 0-5℃
Desheng Technology has more than ten years of R&D, production, and sales experience in the field of diagnostic raw materials, especially in the development and improvement of new Trinder's reagents of the aniline sodium salt derivative series. It carries out functional groups on the basis of traditional chromogenic substrates. The increase or decrease replaces, continuous optimization and performance improvement are made for the needs of clinical testing!
