2-Phosphonobutane -1,2,4-Tricarboxylic Acid (PBTCA), CAS No. 37971-36-1, is a multifunctional scale and corrosion inhibitor. This listing from Shandong Taihe Water Treatment Co., Ltd. supplies the product as a colourless to light yellow transparent liquid with a minimum active acid content of 50.0%. Its molecular formula is C7H11O9P with a molecular weight of 270.13, and it has a minimum density of 1.27 g/cm3 at 20°C and a pH range of 1.5 to 2.0 for a 1% solution.
PBTCA combines the structural features of both phosphoric acid and carboxylic acid groups. This dual functionality provides effective scale and corrosion inhibition, particularly noted for superior performance under high-temperature conditions compared to some organophosphines. It also improves the solubility of zinc salts and demonstrates good tolerance to chlorine oxidation, making it a versatile component in composite formulations. Typical industry applications leverage these properties in demanding water treatment scenarios.
The primary applications are in circulating cooling water systems and oilfield refill water, where it acts as a stabiliser for zinc salts and is often combined with copolymers or other water treatment chemicals. It is also used in high-temperature, high-hardness, high-alkali, and high-concentration-index conditions. The recommended standalone dosage is 5-15 mg/L. For sourcing, the product is typically packaged in 250kg net plastic drums, with IBC drums available upon request. Storage is advised in a shady, dry place at room temperature for up to one year.

Before placing an order for PBTCA from Shandong Taihe Water Treatment Co., Ltd., verify the exact active acid content and impurity levels (phosphorous acid) for the specific batch. Request the current Certificate of Analysis (CoA) and the full Safety Data Sheet (SDS) to ensure the product meets your technical and regulatory requirements. Clarify the exact packaging dimensions and weight for logistics planning.
Confirm all trade terms directly with the supplier. This includes the minimum order quantity (MOQ), which is not specified in the listing, as well as pricing, payment terms, and the applicable Incoterms (e.g., FOB, CIF). Lead times for production and shipment from Zaozhuang, Shandong, must be agreed upon in writing. Since the supplier's response metrics are not available, establish a clear communication channel for order tracking.
Upon receipt, conduct quality checks on the liquid's appearance (colour and clarity) and density. A simple pH check of a 1% solution should fall within the 1.5-2.0 range. For critical applications, consider third-party laboratory verification of the active content and key impurity limits against the CoA. Ensure storage conditions are met immediately upon delivery to preserve the product's shelf life.
