Description

2-Ethoxy-5-(4,5-Dihydro-3-Heptadecyl-5-Oxo-1H-Pyrazol-1-Yl)Benzenesulphonic Acid is a high-purity, functionalized benzenesulfonic acid derivative designed for advanced chemical synthesis. This compound serves as a critical intermediate or functional additive, offering unique reactivity due to its integrated pyrazolone and long-chain alkyl groups. It is essential for research and development laboratories and industrial manufacturers in the pharmaceutical, agrochemical, and specialty chemical sectors seeking to develop novel active ingredients or performance materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, particularly those targeting specific biological pathways.
• Agrochemical Synthesis: Used in the research and production of advanced herbicides, fungicides, or plant growth regulators.
• Specialty Chemical Production: Serves as a precursor for dyes, pigments, and functional polymers requiring specific sulfonic acid groups.
• Research & Development: A valuable tool in medicinal chemistry and material science for structure-activity relationship (SAR) studies.
• Surfactant & Detergent Chemistry: The long alkyl chain and sulfonic acid group make it a candidate for developing specialized anionic surfactants.
• Ligand & Catalyst Design: Potential use in creating complexing agents or ligands for metal catalysis in organic transformations.

Quality Control

Our 2-Ethoxy-5-(4,5-Dihydro-3-Heptadecyl-5-Oxo-1H-Pyrazol-1-Yl)Benzenesulphonic Acid is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications. A Certificate of Analysis (COA) detailing all test results is provided with each shipment, ensuring full traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled 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. Keep away from strong bases and oxidizing agents.
