Chromogen substrates play an important role in the in vitro diagnostic industry. Trinder ’s reagents are one of the most common in vitro diagnostic reagents, mainly divided into traditional Trinder ’s reagents and new Trinder ’s reagents. The traditional Trinder ’s reagents mainly include phenols and anilines, and the new Trinder ’s reagents are highly water-soluble aniline derivatives. Due to their high water solubility, high color sensitivity and high stability, they are widely used in clinical detection and biochemical experiments.

The new Trinder's reagents can form an oxidative coupling reaction with 4-aminoantipyrine (4-AA) or 3-methylbenzothiazole sulfone hydrazone (MBTH) in the presence of hydrogen peroxide and peroxidase. The very stable purple or blue dye can be used in both solutions and test line inspection systems, and is used in many inspection items.

New Trinder's reagents include DAOS, TOOS, TOPS, DAOS, ALPS, DAOS, MADB, HDAOS, etc., among which TOOS and TOPS are more commonly used.

Yacoo Science is a national high-tech enterprise with strong R & D strength and superb production technology.

 It has a product system dominated by "in vitro diagnostic reagent raw materials", "electrochemical new materials", "biological buffers", and "medical intermediates" ,and can provide high purity, good stability of in vitro diagnostic reagent products, including DAOS, TOOS, TOPS, MAOS and other new Trinder's reagents.

TOOS, 3-(N-ethyl-methylanilino)-2-hydroxy propane sulfonic acid, Sodium Salt, it is a white crystalline powder, its CAS number is 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 and glycated albumin detection kits.

TOPS, N-ethyl-N-(3-sulfopropyl)-m-toluidine sodium salt, is a white powder, its CAS number is 40567-80-4, it is mainly used for uric acid determination, blood creatinine detection, etc. Renal function diagnostic kits.
