For procurement managers and R&D scientists in the chemical and pharmaceutical industries, sourcing essential raw materials efficiently and reliably is a constant challenge. 4-Aminobenzoic Acid (PABA), identified by CAS number 150-13-0, is one such compound that plays a vital role in various synthesis processes. This article aims to provide a practical guide for buyers looking to purchase PABA, focusing on critical specifications, common applications, and strategies for finding dependable manufacturers and suppliers.

PABA (C7H7NO2) is characterized by its appearance as a white crystalline powder. Its primary utility lies in its function as a versatile intermediate. In the pharmaceutical sector, it is a key building block for synthesizing anesthetic drugs and is crucial in the production of folic acid. The stringent quality requirements for pharmaceutical applications necessitate sourcing PABA with a high assay, typically 99% or above, and compliance with pharmacopoeial standards like USP and BP. Buyers often search for terms such as 'buy PABA CAS 150-13-0' or 'pharmaceutical intermediate PABA price' to initiate their procurement process.

Beyond its pharmaceutical applications, PABA is also utilized in the dye industry and historically served as a sunscreen ingredient due to its UV-absorbing properties. This broad range of applications means that PABA is sought after by diverse industries, underscoring the need for a stable and competitive supply chain. When considering a purchase, understanding the typical specifications provided by manufacturers is crucial. These often include the appearance, assay percentage (e.g., ≥99.5%), loss on drying, melting point (around 186-189°C), and residue on ignition.

For bulk purchases, engaging directly with manufacturers and suppliers is the most effective strategy to secure favorable pricing and ensure consistent supply. Buyers looking for 'PABA supplier in China' or 'chemical manufacturer PABA' are seeking economies of scale and reliable production capacity. Requesting a quote from multiple suppliers allows for price comparisons and negotiation, ensuring you obtain the best value for your investment. Packaging details, commonly 25kg/drum, are also important logistical considerations.

In conclusion, sourcing 4-Aminobenzoic Acid requires a strategic approach. Prioritize suppliers who can demonstrate consistent quality, meet stringent purity requirements, and offer competitive pricing for bulk orders. By focusing on these aspects and leveraging the power of targeted online searches for 'PABA manufacturer' or 'purchase CAS 150-13-0', businesses can establish robust supply chains for this essential chemical intermediate. We are a prominent manufacturer and supplier, ready to meet your demands for high-quality PABA and provide you with a competitive quotation.
