Description

Selenourea is a versatile organoselenium compound with the molecular formula CH4N2Se, serving as a critical reagent and precursor in advanced chemical synthesis. Its primary commercial value lies in its role as a highly effective selenium source for the preparation of metal selenide nanoparticles and semiconductor materials. This product is essential for research and production in the fields of pharmaceuticals, materials science, and fine chemical manufacturing, where precise selenium incorporation is required.

Application

• Semiconductor Precursor: Key selenium source for synthesizing quantum dots (e.g., CdSe, ZnSe) and thin-film solar cell materials (CIGS).
• Pharmaceutical Intermediate: Used in the synthesis of novel selenium-containing drug candidates and bioactive molecules.
• Catalyst & Ligand: Acts as a ligand in coordination chemistry and a catalyst in organic transformations.
• Analytical Reagent: Employed in analytical chemistry for selenium determination and as a derivatization agent.
• Chemical Synthesis: Fundamental building block for introducing the selenocarbonyl (C=Se) functional group into organic molecules.
• Polymer & Material Science: Used in the development of specialized polymers and functional materials with unique electronic properties.

Quality Control

Our Selenourea is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive quality assurance, including testing for identity, assay, and impurity profiles. A detailed Certificate of Analysis (COA) is supplied with each shipment, confirming compliance with agreed specifications. For specialized applications, we can tailor quality control parameters to meet specific GMP or research-grade requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
