Description

4-Amino-1,2-Dihydro-1,5-Dimethyl-3-Oxo-2-Phenyl-3H-Pyrazolium Dihydrogen Phosphate is a high-purity, organophosphate salt derivative of a pyrazolone base, valued for its role as a key synthetic intermediate and active pharmaceutical ingredient (API) precursor. Its significance lies in providing a stable, crystalline form of the bioactive pyrazolone moiety, which is crucial for ensuring consistent performance in downstream synthesis. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and fine chemical sectors who require a reliable building block for developing novel therapeutic and specialty chemical agents.

Application

• Pharmaceutical Intermediate: Serves as a critical precursor in the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs) and other analgesic or antipyretic agents.
• Agrochemical Synthesis: Used as a building block for developing novel pesticides, herbicides, and plant growth regulators.
• Biochemical Research: Acts as a substrate or inhibitor in enzymatic studies and biochemical pathway analysis.
• Fine Chemical Production: Employed in the manufacture of dyes, pigments, and complex organic compounds requiring a functionalized pyrazolone core.
• Analytical Reference Standard: Supplied as a high-purity standard for quality control and analytical method development in regulatory and R&D laboratories.

Quality Control

Our 4-Amino-1,2-Dihydro-1,5-Dimethyl-3-Oxo-2-Phenyl-3H-Pyrazolium Dihydrogen Phosphate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and titration methods, to ensure high purity and batch-to-batch consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all specifications and test results. Our production adheres to cGMP principles where applicable, supporting its use in regulated pharmaceutical development.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong oxidizing agents.
