Description

Phosphoric Acid CAS NO 790712-60-6 is a fundamental inorganic acid and a critical industrial chemical with a wide range of applications. Its primary value lies in its versatility as a pH adjuster, chelating agent, and source of phosphorus in numerous manufacturing processes. This product is essential for industries including food and beverage production, water treatment, metal surface treatment, and fertilizer manufacturing. We supply high-purity grades to meet the stringent requirements of global industrial and technical applications.

Application

• Food & Beverage Industry: Used as an acidulant and flavor enhancer in soft drinks (cola), jams, and processed cheeses; also serves as a sequestrant.
• Water Treatment: Acts as a corrosion inhibitor and scale prevention agent in potable water and industrial water systems.
• Metal Treatment & Surface Finishing: Key component in phosphating solutions for rust-proofing and preparing metal surfaces (e.g., steel, aluminum) for painting or coating.
• Fertilizer Production: A primary raw material for manufacturing phosphate fertilizers such as monoammonium phosphate (MAP) and diammonium phosphate (DAP).
• Chemical Synthesis: Serves as a catalyst, pH adjuster, and intermediate in the production of detergents, ceramics, and other phosphorus-containing chemicals.
• Pharmaceutical & Personal Care: Employed in dental etching gels, as a pH buffer in topical formulations, and in some cleaning products.
