Description

5-(Phosphonomethyl)Isophthalic Acid is a multifunctional organic compound featuring both phosphonic and carboxylic acid groups on an aromatic core. This unique bifunctional structure makes it a valuable intermediate for synthesizing advanced materials and specialty chemicals. It is particularly sought after by research institutions and manufacturers in the pharmaceutical, agrochemical, and polymer industries for developing novel chelating agents, scale inhibitors, and functional monomers.

Application

• Pharmaceutical Intermediate: Serves as a key building block for synthesizing novel drug candidates, particularly those requiring metal-chelating or bone-targeting properties.
• Agrochemical Synthesis: Used in the production of advanced herbicides and plant growth regulators that leverage its phosphonate functionality.
• Polymer & Material Science: Acts as a functional monomer for creating specialty polymers, coatings, and resins with enhanced adhesion, corrosion resistance, or flame-retardant characteristics.
• Chelating Agent Precursor: A vital intermediate for manufacturing high-performance chelating agents and water treatment chemicals used in industrial cleaning and scale inhibition.
• Research & Development: Employed in academic and industrial R&D for exploring new organophosphorus compounds and metal-organic frameworks (MOFs).
• Surface Modification: Utilized to functionalize surfaces and nanoparticles, imparting specific chemical reactivity or biocompatibility.

Quality Control

Our 5-(Phosphonomethyl)Isophthalic Acid is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity assessment and NMR for structural confirmation, to ensure it meets precise customer specifications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
