For professionals working with dyes and colorants, a thorough understanding of technical specifications is crucial for successful application and procurement. Solvent Red 24, identified by its CAS number 85-83-6, is no exception. This prominent azo dye, often referred to as Sudan IV, possesses a distinct set of chemical and physical properties that dictate its performance across various industries.

The chemical identity of Solvent Red 24 is encapsulated by its molecular formula, C24H20N4O, and a molecular weight of approximately 380.44 g/mol. These fundamental parameters are critical for chemists and formulators when calculating dosages and ensuring compatibility within complex mixtures. Its structure, featuring a bis-azo linkage and a naphthol group, contributes to its characteristic red-brown color and its solubility in organic media.

When aiming to buy Solvent Red 24 online, paying close attention to purity is paramount. While various grades exist, industrial applications typically require a high level of purity to ensure consistent coloration and avoid unwanted side reactions. Manufacturers often specify purity levels, for example, `dye content >90%` or `purity >95%`, depending on the intended use. For sensitive applications like biological stain Sudan IV, even higher purity grades are often necessary to achieve clear and unambiguous results.

The physical form of Solvent Red 24 is typically described as a powder or solid, with a color ranging from dark red to brown. This physical characteristic is important for handling, storage, and dispersion during manufacturing processes. Its insolubility in water, coupled with its solubility in solvents like benzene, methanol, and acetone, clearly defines its utility as a 'solvent' dye, making it ideal for coloring non-aqueous systems such as plastics, oils, and inks.

The importance of sourcing from reliable suppliers cannot be overstated. Businesses actively seeking Solvent Red 24 manufacturers China or other global regions must scrutinize product specifications. Factors such as melting point (around 199 °C with decomposition), stability, and resistance to degradation are all critical data points. Understanding these technical details ensures that the chosen dye will perform as expected, whether it's for robust plastics coloring or delicate laboratory analysis.

In conclusion, the technical specifications of Solvent Red 24 provide essential insights into its application potential and performance characteristics. By meticulously reviewing these details, from molecular formula to purity levels, users can make informed decisions, ensuring the successful implementation of this versatile dye in their industrial processes or research endeavors. Accurate information is key to harnessing the full capabilities of this vibrant azo dye.
