In the realm of analytical chemistry, precision and accuracy are paramount. Cupferron (CAS 135-20-6) stands out as a critical reagent, enabling precise elemental analysis across a wide spectrum of metals. For laboratories and research institutions looking to buy Cupferron, understanding its analytical applications and sourcing from reliable suppliers is key.

The Role of Cupferron in Elemental Analysis

Cupferron, chemically known as ammonium N-nitroso-N-phenylhydroxylamine, functions as a chelating agent. This means it can form stable, insoluble complexes with various metal ions. The formation of these complexes allows for the quantitative determination of specific elements through gravimetric analysis (weighing the precipitate) or colorimetric methods. Its efficacy spans a range of metals, making it a versatile tool for analytical chemists. Key elements for which Cupferron is commonly used include:

  • Aluminum (Al)
  • Bismuth (Bi)
  • Copper (Cu)
  • Iron (Fe)
  • Mercury (Hg)
  • Zinc (Zn)
  • Manganese (Mn)
  • Niobium (Nb)
  • Gallium (Ga)
  • Tantalum (Ta)
  • Thorium (Th)
  • Titanium (Ti)
  • Vanadium (V)
  • Tin (Sn)

The reliability of these analyses hinges on the purity of the Cupferron used. A high assay, typically ≥99.0%, ensures that the reagent itself does not introduce significant errors or side reactions. When you purchase Cupferron, always check its specifications and request a Certificate of Analysis (COA) from your Cupferron supplier.

Sourcing High-Quality Cupferron

When sourcing Cupferron, especially for critical analytical work, it is advisable to connect with a reputable Cupferron manufacturer who specializes in high-purity chemicals. Many leading suppliers, often based in China, offer Cupferron with guaranteed assay percentages and detailed documentation. When inquiring about Cupferron for sale, ask about lot-to-lot consistency and storage recommendations to maintain its efficacy. The availability of technical data sheets (TDS) and safety data sheets (SDS) is also crucial for proper handling and application.

Beyond Analysis: Other Applications

While its analytical prowess is a primary draw, Cupferron also serves as a polymerization inhibitor and an antioxidant. These properties contribute to its value in various industrial formulations, protecting materials from degradation and unintended reactions. For industrial chemists, sourcing Cupferron from a reliable provider ensures a consistent supply for these diverse needs.

In conclusion, Cupferron (CAS 135-20-6) is an indispensable reagent for precise elemental analysis. Its ability to chelate a wide array of metal ions makes it a cornerstone in many analytical laboratories. By prioritizing purity and sourcing from trusted manufacturers and suppliers, users can ensure the accuracy and reliability of their analytical results.
