Description

Neocuproine Hydrochloride is a high-purity chemical reagent primarily recognized as a highly selective and sensitive chromogenic agent for the spectrophotometric determination of copper(I) ions. Its value lies in its ability to form a stable, orange-colored complex with Cu(I), making it indispensable for precise analytical chemistry applications. This compound is critically needed by research laboratories, pharmaceutical quality control units, and industrial facilities involved in environmental monitoring, metallurgy, and catalyst research where accurate copper quantification is paramount.

Application

• Spectrophotometric Analysis: Primary use as a selective chromogenic reagent for the colorimetric detection and quantification of cuprous (Cu(I)) ions in solution.
• Biochemical Research: Used in studies of copper-containing enzymes and proteins, and as a tool to probe biological redox processes involving copper.
• Pharmaceutical QC: Employed in analytical methods for testing raw materials, intermediates, or finished products for trace copper impurities.
• Environmental Testing: Applied in assays to measure bioavailable copper levels in water, soil, and industrial effluent samples.
• Material Science: Utilized in the development and analysis of copper-based catalysts, nanomaterials, and electronic materials.
• Food & Beverage Analysis: Can be part of methods to determine copper content in foodstuffs and nutritional supplements.

Quality Control

Our Neocuproine Hydrochloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity verification and identity confirmation by FT-IR and melting point determination, to ensure it meets the high standards required for analytical and research applications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container should be kept in a desiccated environment to prevent moisture absorption, which can affect performance and stability.
