Manufacturing Quality Control of ETHYL 1H-INDAZOLE-7-CARBOXYLATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorption at specific wavelength using reverse-phase chromatography with external standard calibration. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient reverse-phase HPLC with UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., ethanol, ethyl acetate) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration based on iodine-sulfur dioxide redox reaction. |
| Heavy Metals | ICP-MS | Quantifies trace metal impurities (e.g., Pb, Cd, Ni) by inductively coupled plasma mass spectrometry after acid digestion. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after high-temperature oxidation of sample with sulfuric acid pretreatment. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using controlled heating and visual observation. |
| Appearance | Visual Inspection | Assesses physical state, color, and homogeneity against defined reference standards under controlled lighting. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution by analyzing angular scattering pattern of laser beam passing through dispersed sample. |
| Specific Optical Rotation | Polarimetry | Determines chiral purity by measuring angle of rotation of plane-polarized light in solution. |
| Residual Palladium | ICP-OES | Quantifies palladium catalyst residues using inductively coupled plasma optical emission spectroscopy after microwave digestion. |
