CAS No. 71050-62-9 Phosphino-Carboxylic Acid, also known as Poly(carboxylic acid) or PCA, is a water-soluble organic phosphonate supplied by Shandong Longtaili Science And Technology Co.,ltd. The compound has the molecular formula (C3H4O2·H3O2P·Na)x and is delivered as a light yellow transparent viscous liquid. It is stored at 2-8°C to maintain stability and exhibits a slight odor with an active content of 40% or 50% as acid.
This polycarboxylic acid is formulated to function as a scale and corrosion inhibitor, particularly in cooling circulation water systems and boilers. Its chelating properties allow it to bind metal ions, preventing scale formation and protecting equipment from corrosion. Typical industry standards for PCA include a pH range of 3.5-4.5 for a 1% solution and a density of 1.15-1.25 g/cm³ at 20°C, which are critical for its performance in water treatment applications.
Primary applications extend beyond water treatment to include use as a metal chelate agent and color-fixing agent in textile printing, as well as a complexing agent in electroplating and a cleaning agent for metal water scales. Industrial buyers, such as water treatment plants and textile manufacturers, source PCA for its multifunctional role in maintaining system efficiency. Bulk shipments are typically handled in IBC tanks or drums, with packaging and lead times confirmed directly with Shandong Longtaili Science And Technology Co.,ltd.

Before ordering CAS No. 71050-62-9 Phosphino-Carboxylic Acid from Shandong Longtaili Science And Technology Co.,ltd., verify the active content percentage, pH range, and density to ensure compatibility with your water treatment or textile processes. Request a certificate of analysis to confirm these specifications, as well as any third-party test reports for heavy metals or other contaminants. Ensure the supplier can provide documentation for compliance with local environmental regulations.
Logistics for PCA require temperature-controlled shipping to maintain its stability, as the compound degrades at temperatures above 8°C. Discuss lead times, incoterms (e.g., FOB Qingdao or CIF to your port), and payment terms with the supplier. Clarify whether the packaging includes insulated containers or refrigeration to prevent temperature fluctuations during transit.
Quality checks should focus on the active content, viscosity, and pH of the delivered product, as these directly impact its effectiveness. Inspect the packaging for leaks or damage upon arrival, and consider arranging a pre-shipment inspection for large orders. For applications in regulated industries, such as drinking water treatment, confirm that the supplier’s PCA meets the relevant safety and purity standards.
