PRODUCT OVERVIEW

Product Description

PBTC (2-Phosphonobutane-1,2,4-Tricarboxylic Acid) is an organophosphorus raw material supplied in the referenced grade as a clear, colorless to pale-yellow aqueous solution. The material is used in selected industrial water-treatment and formulated cleaning applications where metal-ion complexation, mineral-deposit control, and formulation stability are important. The referenced 50% grade is defined by controlled active-acid content, phosphorous and phosphoric acid limits, pH, density, iron, and chloride specifications. Product compatibility, permitted applications, handling requirements, and technical performance should be confirmed using the current supplier SDS, COA, and applicable industrial regulations before commercial use.
