The Chemistry of Color: Understanding Basic Red 2 and Its Properties
Basic Red 2, chemically known as Safranine O (CAS 477-73-6), is a fundamental synthetic dye that plays a critical role in various industrial coloring processes. Its unique chemical structure and properties contribute to its effectiveness in applications such as paper coloring, textile dyeing, and the creation of organic pigments. For chemists, formulators, and procurement specialists, a deep understanding of its characteristics is vital. If you are looking to buy Basic Red 2, grasping its technical profile is the first step to successful integration into your products.
The molecular formula for Basic Red 2 is C20H19ClN4, with a molecular weight of approximately 350.85 g/mol. It typically presents as a solid, often described as a dark red to violet powder, and maintains a high purity, with assays commonly reaching ≥99.0%. This high purity is critical for ensuring consistent color intensity and performance in its applications, particularly when used in the preparation of color lake organic pigments where precise formulation is key.
Key properties that influence its industrial utility include its solubility characteristics and pH behavior. While soluble in water, yielding a red color, it also dissolves in ethanol with a fluorescent red hue. Its pH in aqueous solution (10g/l, H2O, 20℃) is typically around 10, indicating its basic nature. The melting point is reported as >240℃ with decomposition, suggesting thermal stability within typical processing temperatures for many applications.
The application range of Basic Red 2 is broad, underscoring its industrial importance. In the paper industry, it's used for effective paper coloring. For textiles, it dyes acrylic fibers, hemp, and silk with good results. Its role in creating organic pigments is also significant, contributing to vibrant colors in inks and coatings. For those involved in R&D, understanding how these properties translate into end-product performance is essential.
