Manufacturing Quality Control of 850583-75-4
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at characteristic wavelength based on peak area comparison to reference standard. |
| Related Substances | HPLC-DAD | Detects and quantifies structurally related impurities using diode array detection for spectral confirmation and peak integration against reference standards. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents by gas chromatography with flame ionization detection using internal or external calibration. |
| Heavy Metals | ICP-MS | Measures trace metal contaminants (e.g., Pb, Cd, Ni, Cr) via inductively coupled plasma mass spectrometry after acid digestion and dilution. |
| Chloride Content | Ion Chromatography | Determines chloride ion concentration by suppressed conductivity detection after anion exchange separation. |
| Moisture Content | Karl Fischer Titration | Measures water content volumetrically or coulometrically via iodine-sulfur dioxide redox reaction in anhydrous methanol medium. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using controlled heating and visual observation of phase change. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under standardized white light and against reference standards. |
| Solubility Profile | Qualitative Solubility Test | Evaluates dissolution behavior in specified solvents (e.g., chloroform, THF, DMF) by visual assessment of clarity and residue after agitation and settling. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content by ignition at 700-800 C followed by weighing of residual non-volatile matter. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of dry powder using Mie scattering theory applied to laser light diffraction patterns. |
| Bulk Density | Tap Density Measurement | Calculates mass per unit volume of powder after standardized tapping cycles using a calibrated graduated cylinder and analytical balance. |
