Scientific research, whether in academic institutions or industrial R&D departments, relies heavily on precision and reproducibility. Central to many laboratory procedures is the ability to maintain stable chemical environments, particularly consistent pH levels. Sodium Dihydrogen Phosphate Dihydrate (CAS 13472-35-0) is a cornerstone reagent, widely utilized in the preparation of buffer solutions that are indispensable for a vast array of experiments.

As a manufacturer and supplier of high-purity chemicals, we understand the critical importance of Sodium Dihydrogen Phosphate Dihydrate for the scientific community. Its well-defined properties and excellent buffering capacity make it a reliable choice for researchers across disciplines like biochemistry, molecular biology, and analytical chemistry.

The Science of Buffering

A buffer solution resists changes in pH when small amounts of acid or base are added. Sodium Dihydrogen Phosphate Dihydrate, when paired with its conjugate base, Disodium Hydrogen Phosphate, forms a highly effective phosphate buffer system. This system is particularly valuable as it can maintain pH in the biologically relevant range, typically around neutral pH values. This stability is crucial for:

  • Enzyme Activity: Enzymes, the biological catalysts of life, are highly sensitive to pH. Maintaining an optimal pH range is critical for their proper function and reaction rates.
  • Cell Culture: Cultured cells require a stable pH environment to survive and proliferate. Phosphate buffers are standard in cell culture media.
  • Electrophoresis: In techniques like gel electrophoresis, buffers are used to maintain a stable electric field and ensure accurate separation of biomolecules based on size and charge.
  • Chromatography: Mobile phases in various chromatographic techniques often require precise pH control for optimal separation and detection of analytes.

Procuring High-Purity Reagents

For laboratory use, the purity of Sodium Dihydrogen Phosphate Dihydrate is paramount. Impurities can interfere with sensitive experiments, leading to inaccurate results or failed procedures. We emphasize sourcing and supplying Sodium Dihydrogen Phosphate Dihydrate that meets stringent laboratory-grade specifications. Procurement managers should look for:

  • Assay Purity: High purity levels (e.g., >99%) are essential.
  • Low Contaminants: Absence of heavy metals, organic impurities, and other interfering substances.
  • Consistent Quality: Batch-to-batch consistency ensures reproducibility in experimental outcomes.
  • Reliable Supply: Ensuring a steady availability of this critical reagent prevents research disruptions.

By partnering with trusted chemical suppliers who provide high-purity Sodium Dihydrogen Phosphate Dihydrate, laboratories can ensure the accuracy and reliability of their scientific endeavors. Its role as a fundamental buffer underscores its significance in advancing scientific knowledge and innovation.
