Chromogen substrates play an important role in in vitro diagnostic industry. Trinder's reagent is one of the most common in vitro diagnostic reagents, which mainly includes traditional Trinder's reagent and new Trinder's reagent. Traditional Trinder's reagents mainly include phenols such as phenol and aniline, while new Trinder's reagents are highly water-soluble aniline derivatives, which are widely used in clinical detection and biochemical experiments due to their high water solubility, high color sensitivity and high stability.

In the presence of hydrogen peroxide and peroxidase, the new Trinder's reagent can react with 4-aminoantipyrine (4-AA) or 3-methylbenzothiazolylsulfonylhydrazone (MBTH) to form a very stable purple or blue dye. It can be used in both solution and test line detection system, and can be used in many detection items.

New Trinder's reagents include Daos, toos, tops, Maos, Alps, ADOS, MADB, hdaos, etc., among which toos and tops are more commonly used.

Desheng is a new technology enterprise specializing in the research, development, production and sales of in vitro diagnostic reagents. We have excellent quality product system dominated by "in vitro diagnostic reagent raw materials", "blood collection additive", "biological buffer" and "chemiluminescence reagent", which can provide high purity and good stability in vitro diagnostic reagent products, including Daos, toos, tops, Maos and other new Trinder's reagents. Now expand the new products carbomer and nucleic acid detection core material virus preservation solution, customer response is also very good.

Toos and tops are Desheng's "star products", with high color sensitivity, strong stability and good user experience. Toos Chinese name n-ethyl-n - (2-hydroxy-3-sulfopropyl) - 3-methylaniline sodium salt, CAS No. 82692-93-1, appearance of white crystalline powder. In the field of in vitro diagnosis, it is mainly used for the detection of blood glucose metabolism, such as the preparation of glucose detection kit, glycosylated albumin detection kit, etc.

Structure diagram of tops (cas40567-80-4)

The Chinese name of tops is n-ethyl-n - (3-sulfopropyl) m-toluidine sodium salt. The CAS number is 40567-80-4. The appearance of tops is white powder. It is mainly used in uric acid determination, serum creatinine detection and other renal function diagnostic kits.
