High-purity thiourea

Product Overview

High-purity thiourea (molecular formula: SC(NH₂)₂, CAS No.: 62-56-6) is a white, lustrous crystalline substance with a bitter taste. It is readily soluble in water and has distinctive reducing and complexing properties. It is an upgraded, further-processed product derived from standard industrial-grade thiourea. By strictly controlling impurity levels, it achieves a purity far exceeding conventional standards.

Compared with industrial-grade thiourea, the key advantage of high-purity thiourea is its extremely low levels of metal-ion impurities (such as sodium, potassium, iron, and copper) and anionic residues. This makes it indispensable in technology sectors that are highly sensitive to impurities, and a key fine chemical connecting basic chemicals with high-value-added industries.

Key Advantages

1. Electronics and Semiconductor Industries

High-purity thiourea offers significant value in this field. Trace metal ions in standard thiourea can have a catastrophic impact on semiconductor device performance. With its extremely low impurity content, high-purity thiourea ensures that no contaminants are introduced during cleaning, etching, and deposition processes, making it a key material for ensuring high chip yields. High-purity thiourea has become a customized choice for applications such as semiconductor plating baths and electronic adhesives.

2. Pharmaceutical Synthesis

In pharmaceutical synthesis, high-purity thiourea serves as an intermediate or catalyst. It produces fewer side reactions and is easy to purify, helping ensure high drug purity and safety. Global demand for thiourea in the pharmaceutical intermediates sector is continuing to grow at a compound annual growth rate of approximately 7.5%.

3. Precision Electroplating

The low impurity content of high-purity thiourea helps prevent plating bath aging and decomposition, as well as the formation of impurity deposits. This results in coatings that are denser, brighter, and more uniform, with stronger adhesion, meeting the stringent requirements of precision electroplating.

4. Scientific Research

In research, the reliability of high-purity thiourea eliminates anomalous experimental results caused by raw material impurities, ensuring data accuracy and scientifically sound conclusions.
