For industries relying on specific chemical intermediates, understanding the detailed specifications and quality benchmarks is crucial for successful production. 4-Aminobenzoic Acid (PABA), identified by its CAS number 150-13-0, is a prime example of such a compound. While known for its high-purity pharmaceutical grades, industrial applications also demand specific quality standards to ensure performance and cost-effectiveness. This guide delves into what industrial buyers should look for when sourcing PABA.

Industrial-grade 4-Aminobenzoic Acid, while perhaps not requiring the absolute highest purity levels of pharmaceutical grades, still adheres to strict specifications. Typically, the appearance is a white crystalline powder. The assay, a measure of the substance's purity, is a key parameter. For industrial use, an assay of ≥99.0% is common and sufficient for many applications, including dye synthesis and certain fine chemical processes. Suppliers offering PABA often list detailed specifications such as Loss on Drying (≤0.5%), Melting Point (186~189°C), and Residue on Ignition (which may have a slightly higher tolerance than pharma grades, for example, ≤0.3%). These parameters ensure the product's stability and suitability for its intended industrial function.

The demand for PABA in industrial settings primarily stems from its role as an intermediate. In the dye industry, it's a critical component for producing specific azo dyes. Its structural features allow for various chemical reactions that yield colored compounds used in textiles, inks, and pigments. Furthermore, in fine chemical synthesis, PABA acts as a versatile building block for creating more complex organic molecules that might find application in agrochemicals, specialized polymers, or other industrial products. Buyers in these sectors often perform searches like 'industrial PABA manufacturer' or 'buy 4-aminobenzoic acid for industrial use' to connect with reliable producers.

When evaluating potential suppliers, buyers should look for manufacturers who provide clear documentation, including Certificates of Analysis (COA) that detail the specific batch's adherence to the stated specifications. For bulk purchases, understanding the packaging (e.g., 25kg/drum) and ensuring reliable logistics is also vital. Companies seeking cost-effective solutions will often compare prices from various manufacturers and suppliers, looking for competitive rates without compromising on essential quality parameters. The sourcing strategy should also consider the supplier's production capacity to ensure they can meet ongoing demand.
