For R&D scientists and chemical engineers, a deep understanding of a chemical's properties is fundamental to its successful application. Solvent Red 1 (CAS: 1229-55-6) is a notable azo dye known for its specific solubility characteristics and industrial utility. This profile provides a technical breakdown of Solvent Red 1, covering its chemical identity, physical properties, and suitability for various technical applications, with insights relevant to sourcing from manufacturers.

Solvent Red 1, chemically identified as 1-[(2-methoxyphenyl)azo]-2-naphthol, possesses the molecular formula C17H14N2O2 and a molecular weight of approximately 278.31 g/mol. As a lysochrome dye, it is designed to color lipids and other non-polar substances. Its physical form is a reddish-orange powder, and a key characteristic is its melting point, which typically falls in the range of 179-183°C. This thermal stability allows it to be incorporated into processes that involve moderate heating without significant degradation.

The solubility profile of Solvent Red 1 is its most defining feature for technical applications. It exhibits good solubility in fats, oils, waxes, and various organic solvents, while remaining insoluble in water. This makes it an excellent choice for coloring applications where water resistance is required. Common technical uses include its incorporation into inks, lacquers, varnishes, plastics (such as polystyrene), and oils. Its ability to disperse evenly within these media ensures a uniform color distribution, which is critical for product consistency and quality control.

When considering the procurement of Solvent Red 1 for technical or research purposes, it is crucial to partner with reliable chemical suppliers. Manufacturers often provide detailed technical data sheets (TDS) that complement the Certificates of Analysis (CoA). These documents offer comprehensive information on solubility, stability, spectral properties, and recommended handling procedures. For businesses seeking to purchase Solvent Red 1, engaging with suppliers in China can offer access to high-purity grades at competitive prices. Key considerations when contacting a manufacturer include inquiring about their quality control processes, available grades, and the possibility of obtaining small quantities for laboratory testing.

In essence, Solvent Red 1 is a valuable chemical intermediate with a well-defined set of properties that lend themselves to specialized industrial and technical applications. A thorough understanding of its chemical and physical characteristics, coupled with diligent supplier selection, will ensure its effective integration into your formulations and processes. For those requiring this dye, exploring options from reputable chemical manufacturers is a strategic step towards achieving desired results.
