For professionals in the pharmaceutical and chemical industries, securing a reliable supply of high-quality 4-Aminobenzaldehyde (CAS 556-18-3) is paramount. This versatile aromatic aldehyde, also known by synonyms like p-Formylaniline, serves as a critical intermediate in numerous synthetic pathways. Understanding the nuances of sourcing this compound can significantly impact the efficiency and success of your projects. As a discerning buyer, you’ll want to focus on purity, consistency, and the reputation of your supplier.

The primary applications of 4-Aminobenzaldehyde lie in its role as a building block for Active Pharmaceutical Ingredients (APIs) and its utility in organic synthesis. Its reactive aldehyde and amine groups make it an ideal starting material for complex molecular constructions. When seeking to buy 4-Aminobenzaldehyde, prioritizing suppliers who offer detailed Certificates of Analysis (CoA) is essential. These documents will confirm the purity, typically specified as 97% min or higher, and provide crucial physical and chemical data such as melting point (77-79°C) and appearance (yellow to orange solid).

The global market offers various options for sourcing this chemical, but identifying a dependable manufacturer in China can provide significant cost advantages without compromising on quality. When evaluating potential suppliers, consider their production capacity, quality control measures, and customer service. For bulk purchases, it's always advisable to request samples to verify the product meets your specific requirements before committing to a large order. Comparing 4-Aminobenzaldehyde prices from different vendors can also help secure the best value for your procurement budget.

Beyond pharmaceuticals, 4-Aminobenzaldehyde finds applications as a dye intermediate and in the development of specialized polymers. Its ability to react with acylating agents to form amides and its use in preparing diazonium salts further highlight its chemical versatility. For R&D scientists and procurement managers alike, establishing a strong relationship with a trusted chemical supplier ensures that crucial intermediates like 4-Aminobenzaldehyde are readily available, facilitating continuous innovation and production.
