For chemists and procurement specialists in the fine chemical sector, understanding the properties and sourcing channels for key intermediates is vital. P-Acetoacetaniside, also known by its CAS number 5437-98-9, is a valuable compound primarily utilized in the synthesis of dyes and pigments. This article provides an overview of its characteristics and offers guidance on how to effectively source this chemical from reliable suppliers.

Understanding P-Acetoacetaniside: Properties and Structure

P-Acetoacetaniside is an organic compound with the molecular formula C11H13NO3. It typically presents as a white to off-white crystalline powder, with a melting point generally falling within the range of 115-118°C. This specific melting point is a critical indicator of its purity and can be a key parameter for quality control when purchasing. Its solubility in common organic solvents like methanol and chloroform, albeit slight, is also noted. The compound's structure consists of an acetoacetyl group linked to a 4-methoxyphenylamine (p-anisidine) derivative, making it a beta-keto anilide. This structural feature is what lends it its reactivity and utility as an intermediate.

Key Applications in Industrial Synthesis

The primary industrial application of P-Acetoacetaniside is its role as a coupling component in the manufacturing of azo dyes and pigments. When reacted with diazonium salts, it forms stable azo compounds that impart color. These colorants find extensive use in various industries, including textiles, printing inks, paints, and plastics. The demand for high-quality P-Acetoacetaniside is directly linked to the performance requirements of these end products. For businesses looking to buy this intermediate, understanding its role in creating specific color shades and ensuring product fastness is essential.

Sourcing Strategies for P-Acetoacetaniside

When sourcing P-Acetoacetaniside, particularly from China, a strategic approach is recommended. Identifying manufacturers that specialize in fine chemical intermediates is key. Look for suppliers who can provide comprehensive technical data sheets (TDS) and certificates of analysis (COA) that detail the product's purity (often specified as 99% min), physical characteristics, and any relevant safety information. When requesting a quote, clearly state your required quantity and any specific packaging needs.

Negotiating prices for P-Acetoacetaniside often involves discussing bulk purchase volumes. Establishing a direct relationship with a manufacturer can lead to better pricing and more reliable supply chains. Furthermore, suppliers who offer technical support or have a strong understanding of chemical synthesis applications can be particularly valuable partners, especially for research and development purposes or when troubleshooting complex formulations.

Regulatory and Safety Considerations

As with any chemical compound, it is important to be aware of the safety data and regulatory compliance for P-Acetoacetaniside. Hazard statements often indicate it is harmful if swallowed (H302). Therefore, appropriate handling procedures, personal protective equipment (PPE), and storage conditions (sealed, dry, room temperature) are necessary. Ensuring your supplier provides accurate safety data sheets (SDS) is a critical part of responsible procurement.

In conclusion, P-Acetoacetaniside is a vital chemical intermediate with well-defined properties and significant industrial applications. By focusing on quality specifications, building relationships with reputable Chinese manufacturers, and understanding its use in synthesis, businesses can efficiently procure this essential compound for their manufacturing needs.
