Industrial Applications of 5-AMINO-1-ETHYLPYRAZOLE
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Key intermediate in the synthesis of non-steroidal anti-inflammatory drugs (e.g., celecoxib, parecoxib) | Serves as a nucleophile in coupling reactions with haloarenes, or for constructing pyrazole ring systems |
| Agrochemicals | Active ingredient or intermediate in insecticide and fungicide synthesis | Used for heterocycle construction or incorporation as a functional side chain |
| Dyes & Pigments | Synthesis of functional dyes or pigments | Acts as a diazo component or coupling component in color-forming reactions |
| Chemical Manufacturing | Organic synthesis building block | Participates in C–N coupling, acylation, or electrophilic substitution reactions |
Manufacturing Quality Control of 5-AMINO-1-ETHYLPYRAZOLE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at ~254 nm. |
| Related Substances (Impurities) | HPLC-UV or UPLC-MS | Separation and detection of structurally related impurities (e.g., starting materials, intermediates, degradants) via retention time and spectral matching; MS provides structural confirmation. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., ethanol, ethyl acetate) based on calibrated response factors. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification of trace metals after acid digestion, leveraging high sensitivity and isotopic resolution for regulatory compliance (e.g., ICH Q3D). |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration measuring water via iodine generation and stoichiometric reaction with water in anhydrous methanol-based medium. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement by observing solid-to-liquid phase change under controlled heating rate; used for identity and purity assessment. |
| Residue on Ignition | Gravimetric Analysis | Determination of inorganic residue after high-temperature ashing (500–600 °C) and weighing; indicates inorganic contaminants or salts. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral molecules in solution; verifies enantiomeric integrity if applicable. |
| pH (1% w/v aqueous suspension) | pH Meter | Electrochemical measurement of hydrogen ion activity in a standardized suspension to assess acid-base character and potential degradation. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns to determine volumetric particle size distribution in dry or dispersed state. |
| Appearance & Color | Visual Inspection / Hazen/APHA Scale | Subjective evaluation against standard color scales (e.g., APHA 10–50) and visual assessment of crystallinity, homogeneity, and foreign particles. |
| Bulk & Tapped Density | Powder Rheometry / Tap Density Tester | Gravimetric determination of mass per unit volume before and after mechanical tapping to assess flowability and compressibility. |
| Microbial Limits | Membrane Filtration / Plate Count | Enumeration of aerobic microorganisms (CFU/g) and absence testing for specified pathogens per pharmacopeial methods (e.g., USP <61>, <62>). |
