Manufacturing Quality Control of 5-methyl-2-Indolinone
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-DAD | Separation and identification of impurities using HPLC coupled with diode array detection; relative retention times and spectral matching support qualification. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common organic solvents based on calibrated external standards. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generation in pyridine-free reagent; endpoint detected by biamperometric or coulometric means. |
| Heavy Metals | ICP-MS | Quantitative determination of trace metals (e.g., Pb, Cd, Hg, As) after acid digestion, using isotopic mass spectrometry for high sensitivity and multi-element capability. |
| Chloride Content | Ion Chromatography | Separation of anions on anion-exchange column with suppressed conductivity detection; chloride quantified via calibration curve. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measured by observing solid-to-liquid phase change in a capillary tube under controlled heating rate. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light induced by chiral centers in solution, reported as degrees per dm·g/mL. |
| Residue on Ignition | Gravimetric Analysis | Mass of inorganic residue remaining after high-temperature ashing (700–800 C) of sample, expressed as weight percent. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of solid material against defined standards under controlled lighting conditions. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity vs. angle to determine volume-based particle size distribution in dry or dispersed state. |
| pH of Aqueous Suspension | pH Meter | Measurement of hydrogen ion activity in a standardized suspension (e.g., 1% w/v in water) using calibrated glass electrode. |
