In the realm of analytical chemistry, precision and sensitivity are paramount. The ability to accurately quantify specific analytes is fundamental to quality control, research, and various industrial processes. Among the array of specialized reagents available, 1,10-Phenanthroline Hydrochloride Monohydrate (CAS: 18851-33-7) stands out for its efficacy, particularly in the determination of iron.

The Significance of Iron Determination

Iron is a critical element found in numerous applications, from biological systems and environmental samples to industrial materials and food products. Its presence, even in trace amounts, can significantly impact performance, safety, or nutritional value. Consequently, reliable methods for its quantification are constantly sought after by laboratories worldwide.

1,10-Phenanthroline Hydrochloride Monohydrate as a Key Reagent

1,10-Phenanthroline Hydrochloride Monohydrate functions as a highly selective chromogenic reagent for iron. It forms a stable, intensely colored complex with iron (II) ions, typically a reddish-orange or pink hue. This complexation allows for the quantitative analysis of iron using spectrophotometric methods. The intensity of the color, measured at a specific wavelength (usually around 510 nm), is directly proportional to the concentration of iron (II) in the sample, following Beer-Lambert's Law.

The advantages of using this reagent include:

  • High Sensitivity: It allows for the detection of very low concentrations of iron.
  • Selectivity: It shows high specificity for iron (II), with minimal interference from other common ions, especially when properly buffered.
  • Stability: The colored complex formed is relatively stable, allowing time for measurement.
  • Ease of Use: The procedure for preparing samples and performing measurements is generally straightforward.

Procurement for Analytical Applications

For analytical laboratories and researchers, sourcing high-purity 1,10-Phenanthroline Hydrochloride Monohydrate is crucial to ensure accurate and reproducible results. When looking to buy this analytical reagent, it is vital to partner with reputable chemical suppliers and manufacturers who can guarantee strict quality control. Searching for terms like 'buy analytical reagent CAS 18851-33-7' or '1,10-phenanthroline hydrochloride supplier' will help identify trusted sources.

Many leading chemical companies, including those in China, specialize in providing analytical-grade reagents. They ensure that each batch meets stringent specifications for purity and performance, often accompanied by a Certificate of Analysis. NINGBO INNO PHARMCHEM CO.,LTD., for instance, is a recognized supplier of fine chemicals, including specialized reagents like 1,10-Phenanthroline Hydrochloride Monohydrate, catering to the needs of analytical laboratories by providing reliable, high-quality products essential for precise scientific measurements.

In conclusion, the accuracy of many analytical procedures hinges on the quality of the reagents used. 1,10-Phenanthroline Hydrochloride Monohydrate, with its exceptional properties for iron determination, remains an indispensable tool in the analytical chemist's arsenal. Ensuring a reliable supply chain from quality-conscious manufacturers is key to maintaining the integrity of analytical data.
