For procurement managers and R&D scientists in the pharmaceutical and dye industries, sourcing high-quality 4-Chloro-3-nitrobenzoic Acid (CAS: 96-99-1) is paramount. This intermediate plays a crucial role in the synthesis of vital medicines, including anticoagulants like Dabigatran Etexilate, and in the creation of a spectrum of vibrant dyes. Understanding the critical factors when looking to buy this compound can ensure your production runs smoothly and your final products meet exacting standards.

One of the most important specifications to scrutinize is the purity of 4-Chloro-3-nitrobenzoic Acid. Typically, you will find it offered with an assay of 98.0% or higher. For pharmaceutical applications, achieving precise synthesis results hinges on using intermediates with minimal impurities. A reliable manufacturer will provide detailed certificates of analysis (CoA) that clearly state the purity and identify any trace contaminants. When you consider purchasing, always inquire about the CoA to verify it meets your project's requirements.

The primary applications driving the demand for 4-chloro-3-nitrobenzoic acid are its use as a key pharmaceutical intermediate and a precursor in dye manufacturing. In the pharmaceutical sector, it is instrumental in the multi-step synthesis of complex drug molecules. For dye production, its aromatic structure with nitro and chloro substituents allows for the creation of specific chromophores, leading to a wide range of colors. Therefore, identifying a supplier that caters to these specific industry needs is essential.

When searching for a 4-chloro-3-nitrobenzoic acid supplier, consider manufacturers based in regions known for chemical production, such as China. These suppliers often offer competitive pricing due to economies of scale and established supply chains. However, it is crucial to vet potential manufacturers for their quality control processes, production capacity, and track record. Engaging with a reputable manufacturer will ensure not only a consistent supply of high-quality material but also adherence to safety and environmental regulations. For instance, understanding the typical packaging, such as 25 kg drums, and storage requirements, like keeping it in a cool, ventilated place, is also part of the procurement process.

Ultimately, securing a reliable source for 4-chloro-3-nitrobenzoic acid involves a careful evaluation of purity, intended application, and the trustworthiness of the manufacturer. By focusing on these aspects and conducting thorough due diligence, procurement professionals and scientists can confidently purchase this indispensable chemical intermediate, paving the way for successful product development and manufacturing.
