Description

1-(3-Sulfo-4-Phenoxy)-Phenyl-3-Heptadecyl-4-Isopropyl-Pyrazoline-5-One is a high-purity, functionalized pyrazolone derivative, valued for its unique molecular structure that combines a long alkyl chain with a sulfonated phenoxy group. This compound is critical for applications requiring specific chelating, surfactant, or intermediate properties in advanced chemical synthesis. It is primarily sought by manufacturers in the specialty chemical, polymer additive, and research & development sectors for creating performance materials.

Application

• Metal Chelating Agent: Used in formulations for metal extraction, purification, and as a stabilizer in polymer and lubricant systems.
• Specialty Surfactant Intermediate: Serves as a key building block for synthesizing anionic surfactants with specific hydrophilic-lipophilic balance (HLB) properties.
• Polymer Additive: Functions as a light stabilizer, antioxidant, or processing aid in specialty plastics and coatings.
• Chemical Synthesis Intermediate: Utilized in organic synthesis for pharmaceuticals, agrochemicals, and dyes due to its reactive pyrazolone core.
• Analytical Reagent: Employed in research laboratories as a chromogenic agent or complexometric titrant for metal ion detection.
• Cosmetic & Personal Care Ingredients: Potential use in formulating high-end skincare products as a functional active or emulsifier.
