Description

Calcium 1-Naphthyl Phosphate is an organophosphorus compound where the phosphate group is esterified with 1-naphthol and neutralized as a calcium salt. This specialized chemical is valued for its role as a key synthetic intermediate and functional additive in advanced material science and specialty chemical manufacturing. It is primarily sought by R&D laboratories and industrial producers in the pharmaceutical, agrochemical, and polymer industries for developing novel compounds and enhancing material properties.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, particularly where phosphate ester chemistry is required for bioavailability or targeting.
• Agrochemical Synthesis: Serves as a building block for creating novel herbicides, insecticides, and plant growth regulators with specific activity profiles.
• Polymer Additive: Functions as a flame retardant synergist or a plasticizer component in specialized polymer formulations, improving material performance.
• Research & Development: A critical reagent in organic and medicinal chemistry research for constructing complex molecular architectures containing naphthyl and phosphate groups.
• Lubricant & Fuel Additive Precursor: Used in the development of high-performance anti-wear and extreme pressure additives for industrial lubricants and fuels.
• Chelating Agent & Metal Surface Treatment: Employed in formulations for metal cleaning, plating baths, and corrosion inhibition due to its complexing properties.

Quality Control

Our Calcium 1-Naphthyl Phosphate is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including identification (IR), purity assay (HPLC/Titration), and control of key impurities (heavy metals, residual solvents, free naphthol). We provide full traceability and Certificates of Analysis (COA) are available for every shipment to ensure compliance with your specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; containers must be kept tightly sealed and away from direct light sources to maintain stability and purity.
