For professionals involved in chemical procurement, research, or manufacturing, understanding the detailed specifications of a product like Basic Fuchsin (CAS 632-99-5) is crucial for making informed purchase decisions. This vital dye, known for its deep color and broad applicability, requires careful consideration of its technical parameters to ensure it meets the intended use. When you buy Basic Fuchsin, you’re investing in its precise chemical and physical characteristics.

The most critical specification for Basic Fuchsin is its purity, typically indicated by an assay percentage. A standard requirement for many industrial and research applications is a purity level of ≥99.5%. This high purity is essential for applications such as biological staining, where contaminants can interfere with the accuracy of results. For instance, in Gram staining or Ziehl-Neelsen staining, precise dye uptake and differentiation are paramount, making high-purity Basic Fuchsin from a reliable supplier a necessity.

The appearance of Basic Fuchsin is another key characteristic. It is typically described as a dark green crystalline powder. This visual cue, along with its solubility in water and alcohol, helps in confirming the product's identity and quality upon receipt. Buyers should always refer to the product's Certificate of Analysis (CoA) for detailed information on appearance and purity for the specific lot they are purchasing.

The molecular formula, C20H20ClN3, and molecular weight, 337.85 g/mol, are fundamental identifiers that ensure you are procuring the correct chemical compound. These details are standard on supplier datasheets and are critical for any formulation or process development where exact stoichiometry is important. When you seek to buy Basic Fuchsin, verifying these identifiers is a basic but crucial step.

Applications dictate the necessary specifications. For textile dyeing, factors like dye affinity and fastness are key, and while purity matters, slight variations might be acceptable depending on the exact process. However, for biochemical applications, such as staining cell nuclei or detecting polysaccharides, the highest purity is typically demanded. Therefore, when selecting a Basic Fuchsin manufacturer, it’s important to communicate your specific application needs to ensure they can provide a product that meets your exact requirements. Sourcing from a reputable manufacturer, particularly one in China known for its chemical production capabilities, can offer both quality and value, but always prioritize adherence to specifications when making your purchase.
