Hubei Xindesheng exports high-quality color developing substrate DAOS reagent 83777-30-4

In the increasingly competitive global market for in vitro diagnostic reagents, Hubei Xindesheng Material Technology Co., Ltd. has successfully opened the door to the international market and become a trusted partner for laboratories in various regions around the world with its independently developed colorimetric substrate DAOS reagent. As the core component of the new Trinder's reagent, DAOS provides an efficient solution for the field of biochemical detection with its excellent sensitivity, stability, and water solubility.

1, Technological breakthrough: Molecular advantages and color development mechanism of DAOS reagents

The full name of DAOS reagent is N-ethyl-N - (2-hydroxy-3-sulfopropyl) -3,5-dimethoxyaniline sodium salt. The aniline group in its molecular structure endows it with the ability to absorb yellow light, while the sulfonic acid group significantly enhances its water solubility. Under the catalysis of hydrogen peroxide and peroxidase, DAOS undergoes oxidative coupling reaction with 4-aminoantipyrine (4-AA) or 3-methylbenzothiazole sulfone hydrazone (MBTH), generating stable purple or blue dyes with an absorption wavelength precisely locked at 593nm. This characteristic enables high-precision quantitative analysis in spectrophotometers and is widely used for the detection of biomarkers such as glucose, triglycerides, and cholesterol.

DAOS reagents

Hubei Xindesheng Material Technology Co., Ltd. has overcome the purity and stability challenges of DAOS reagents through 20 years of technological accumulation. The purity of its product is over 99%, and the stability of its aqueous solution is significantly better than that of traditional colorants. The scientific preparation, use, and storage methods avoid repeated freeze-thaw cycles, molecular structure damage, or deactivation.

2, Quality assurance: full chain control from research and development to export

Desheng Company strictly follows the international quality management system, implementing full process quality monitoring from raw material procurement to finished product delivery. The DAOS reagent adopts an automated production line to ensure that the purity, solubility, and color development performance of each batch of products meet international standards.

In response to international logistics demands, the R&D team of Hubei Xindesheng has optimized the packaging and storage plan for DAOS reagents. Using light shielded sealed bottles, combined with refrigerated transportation, effectively avoids the impact of repeated freezing and thawing on the activity of reagents. At the same time, each batch of products comes with detailed quality inspection reports and operation guidelines to ensure that overseas customers can quickly get started.

At present, Desheng has established long-term cooperation with more than 20 in vitro diagnostic enterprises in Southeast Asia, the Middle East and other regions, with products covering more than 20 testing items such as blood glucose, blood lipids, and liver function. Its internationalization strategy is not only reflected in product exports, but also extends to technical services - through online training, remote technical support, and other means, it helps overseas customers optimize testing processes and reduce reagent losses.
