Manufacturing Quality Control of 141293-14-3
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 210-220 nm, comparing peak area to reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities by comparing retention times and peak areas against qualified reference standards or threshold-based reporting. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents using capillary GC with flame ionization detection, per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration using iodine generation in pyridine/methanol-based reagent. |
| Heavy Metals | ICP-MS | Measures trace metal contaminants (e.g., Pb, Cd, Ni) after acid digestion via inductively coupled plasma mass spectrometry. |
| Chloride Content | Ion Chromatography | Quantifies chloride ions using suppressed conductivity detection after anion exchange separation. |
| Residual Tert-Butyl Alcohol | GC-FID | Detects residual t-butanol by headspace GC-FID with internal standard calibration. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition 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. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light at 20 °C using sodium D-line to confirm chiral integrity. |
| pH of Aqueous Suspension | pH Meter | Determines pH of a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Loss on Drying | Gravimetric Thermogravimetry | Measures weight loss after drying under controlled temperature and vacuum to determine volatile content. |
