Industrial Applications of 1-(3'-Chlorophenyl)-3-methyl-5-pyrazolone
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Key intermediate for the antipyretic and analgesic drug metamizole (Analgin) | Condensed with 4-methylaminoantipyrine, followed by oxidation and acidification to synthesize metamizole |
| Dyes | Intermediate for azo dyes and metal-complex dyes | Coupled with diazonium salts to produce azo dyes; or complexed with metal ions (e.g., Cr³⁺, Co³⁺) to prepare high-performance metal-complex dyes |
| Pesticides | Synthesis intermediate for certain insecticides and plant growth regulators | Used to construct pyrazolinone-containing active molecules, such as precursors for novel pyrazole-based insecticides |
Manufacturing Quality Control of 1-(3'-Chlorophenyl)-3-methyl-5-pyrazolone
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC-UV; identification relies on retention time matching and relative response factors. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, acetone, toluene) by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine generation and stoichiometric reaction with water. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pb, Cd, As, Hg) after acid digestion using inductively coupled plasma mass spectrometry for ultra-trace sensitivity. |
| Chloride Content | Potentiometric Titration | Measures inorganic chloride ions using silver nitrate titrant and silver/silver chloride indicator electrode based on potentiometric endpoint detection. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light against established reference standards. |
| Loss on Drying | Gravimetric Analysis | Measures volatile loss upon heating at 105 C for 2 h; weight difference before and after drying gives moisture and volatiles content. |
| Residue on Ignition | Sulfated Ash Test | Quantifies non-volatile inorganic residue after high-temperature ignition (600–800 C) following sulfuric acid treatment. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of solid particles in dispersion medium using Mie scattering theory and laser diffraction analysis. |
