The efficacy and quality of many end products in industries like textiles and pharmaceuticals are directly tied to the intermediates used in their synthesis. 4-Nitroaniline (CAS 100-01-6) stands as a prime example of such a critical intermediate, owing to its unique chemical properties and broad applicability. For procurement managers and R&D scientists, understanding these aspects is key to making informed purchasing decisions.

From a physical standpoint, 4-Nitroaniline presents as a yellow crystal, often described as a yellow fine crystal or powder. This visual characteristic is important for quality checks. Its melting point hovers around 147°C, and it has a boiling point of approximately 333.1°C at 760 mmHg. The density is about 1.437 g/cm³. While slightly soluble in water, it shows better solubility in organic solvents like ethanol. Its flash point is relatively high, around 165.0°C, indicating a degree of thermal stability under normal conditions, though it is combustible.

Chemically, 4-Nitroaniline is an aromatic amine substituted with a nitro group at the para position. This structure imparts specific reactivity, making it an excellent precursor for diazotization reactions, which are foundational to the synthesis of azo dyes. The nitro group can also be reduced, leading to diamine compounds that are themselves valuable intermediates. Manufacturers often highlight an assay of ≥98.0% for this product, signifying a high level of purity essential for sensitive synthesis routes.

The applications of 4-Nitroaniline are diverse and impactful. Its role as a dye intermediate is well-established, enabling the production of a spectrum of colors used across various industries. In the pharmaceutical sector, it serves as a building block for synthesizing drug molecules and related compounds, contributing to the development of new therapies and essential medicines. Furthermore, it finds application in the synthesis of antioxidants and as a corrosion inhibitor, showcasing its versatility.

For businesses looking to buy 4-Nitroaniline, partnering with a specialized manufacturer offers significant advantages. A dedicated supplier can provide not only competitive pricing, especially for bulk orders, but also assurance of consistent quality and product traceability. When searching for '4-nitroaniline supplier' or 'buy 4-nitroaniline online', it's crucial to evaluate potential vendors based on their technical expertise, production capacity, and commitment to safety and regulatory compliance. Engaging with a manufacturer can lead to more tailored solutions and a stable supply chain, crucial for uninterrupted production.
