Product Overview

High Purity Thiourea (Molecular Formula: SC(NH₂)₂, CAS No.: 62-56-6) is a white, lustrous crystalline solid with a bitter taste. It is readily soluble in water and possesses unique reducing properties and metal complexation capabilities. As a value-added derivative of standard industrial-grade thiourea, it achieves significantly higher purity levels through rigorous impurity control.

Compared to industrial-grade products, the core advantage of High Purity Thiourea lies in its exceptionally low levels of metal ion impurities (such as sodium, potassium, iron, and copper) and anionic residues. This makes it indispensable in high-technology sectors with stringent purity requirements, serving as a critical fine chemical bridging basic chemicals and high-value-added industries.

Core Advantages

1. Electronics & Semiconductor Industry

High Purity Thiourea delivers exceptional value in this sector. Trace metal ions in standard thiourea can severely compromise semiconductor device performance. With its ultra-low impurity profile, High Purity Thiourea ensures no contamination is introduced during cleaning, etching, and deposition processes—making it a critical material for chip yield assurance. It has become a customized solution for semiconductor plating baths and electronic adhesives.

2. Pharmaceutical Synthesis

In pharmaceutical synthesis, High Purity Thiourea serves as an intermediate or catalyst with minimal side reactions and easy purification, ensuring the final drug product meets stringent purity and safety standards. Global demand for thiourea in pharmaceutical intermediates is growing at a CAGR of approximately 7.5%.

3. High-End Electroplating

The low impurity content of High Purity Thiourea effectively prevents bath degradation, decomposition, and impurity-induced coating defects, producing denser, brighter, more uniform coatings with superior adhesion—meeting the demanding requirements of precision electroplating.
