In the demanding fields of analytical chemistry and cell biology, the quality of reagents is paramount. Fluorexon, also known as Calcein (CAS 1461-15-0), is a vital fluorescent dye used extensively for metal ion determination and cell viability assays. Ensuring the procurement of high-quality Fluorexon is essential for obtaining reliable and reproducible experimental outcomes. This guide aims to assist researchers in navigating the market to find dependable suppliers.

The primary applications of Fluorexon, such as in calcium determination and as an EDTA titration indicator, require a reagent of high purity. Impurities can interfere with the fluorescent signal, lead to false endpoints in titrations, or affect the viability assay results when using derivatives like Calcein AM. Therefore, when looking to buy Fluorexon CAS 1461-15-0, it is crucial to consider the supplier's reputation and commitment to quality control.

When evaluating potential suppliers, several factors should be considered:

  • Purity Specifications: Reputable suppliers will clearly state the purity of their Fluorexon, often through a Certificate of Analysis (CoA). Look for products with high assay percentages (e.g., ≥99%).
  • Supplier Reputation: Research the supplier's history and customer reviews. Established chemical companies with a focus on research reagents are generally more reliable.
  • Manufacturing Standards: For applications requiring stringent quality, such as pharmaceutical research or advanced biological assays, inquire about manufacturing standards like GMP or ISO certifications.
  • Product Documentation: Ensure that comprehensive documentation, including Safety Data Sheets (SDS) and CoAs, is readily available. These documents provide critical information on handling, storage, and analytical specifications.
  • Packaging and Storage Recommendations: Proper packaging and clear storage instructions are indicative of a supplier's attention to maintaining product integrity.

For researchers interested in cellular applications, sourcing Calcein AM, a derivative of Fluorexon, requires similar diligence. The quality of Calcein AM directly impacts the accuracy of cell viability assays and cellular labeling. Understanding the Calcein AM in cell labeling process helps in appreciating the need for a pure and active form of the compound.

The scientific community relies on consistent access to high-quality reagents to advance research. By carefully selecting suppliers and understanding product specifications, researchers can ensure they are using the most effective tools for their demanding experiments. Whether for precise chemical analysis or sophisticated biological studies, investing in quality Fluorexon is investing in the integrity of your scientific findings.

Consulting scientific literature for recommended suppliers or seeking advice from colleagues can also be beneficial when sourcing this essential laboratory chemical.
