In the realm of scientific research, precision and reproducibility are non-negotiable. Every reagent used in experiments, from basic solvents to complex buffers, plays a critical role in achieving reliable results. HEPES buffer (CAS 7365-45-9) is one such compound, widely utilized for its exceptional buffering capabilities in biological and chemical applications. Understanding its specifications, particularly its purity and CAS number, is fundamental for any researcher or procurement specialist.

The Chemical Abstracts Service (CAS) registry number, 7365-45-9, uniquely identifies HEPES, distinguishing it from other chemical compounds. This standardized identification is crucial for accurate sourcing, inventory management, and regulatory compliance. When searching to buy HEPES buffer, referencing this CAS number ensures you are acquiring the correct chemical entity for your intended application, whether it's for biochemical diagnostics, or other specialized uses.

Equally important is the purity of HEPES. For scientific applications, especially in sensitive areas like molecular biology, cell culture, or enzyme kinetics, high purity is paramount. Impurities can interfere with reactions, introduce artifacts, or even exhibit toxicity, leading to skewed data and unreliable conclusions. Many researchers prioritize HEPES with a purity exceeding 99%, a standard often met by reputable manufacturers. A reliable supplier will clearly state the purity level and often provide certificates of analysis to verify the product's quality.

As a vital chemical auxiliary, HEPES is used in numerous kits and assays, including DNA/RNA extraction kits and PCR diagnostic kits. The performance of these kits is directly linked to the quality of the buffer used. Therefore, selecting a manufacturer known for consistent quality control and stable production processes is essential. Many institutions and companies procure their HEPES from suppliers in China, attracted by the combination of high purity, competitive pricing, and the ability to purchase in bulk.

For procurement managers and lab scientists alike, the decision of where to purchase HEPES buffer involves careful consideration of supplier reliability, product specification, and cost-effectiveness. We encourage those in need of this critical buffer to seek out manufacturers who prioritize quality and transparency, ensuring that your research is supported by the most dependable materials available. Exploring options from established chemical suppliers will lead to better experimental outcomes.
