Manufacturing Quality Control of 4-HYDROXYAZEPANE-1-CARBOXYLIC ACID TERT-BUTYL ESTER
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 210-220 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities by gradient HPLC-UV, using relative response factors or reference standards. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, toluene, ethyl acetate) by headspace GC with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine generation in pyridine-free reagent. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pb, Cd, Ni, Cu) after acid digestion using inductively coupled plasma mass spectrometry. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with suppressed conductivity detection. |
| Residual Palladium | ICP-MS | Measures palladium residues from catalytic hydrogenation steps using ICP-MS after microwave-assisted acid digestion. |
| Optical Rotation | [alpha]D Measurement | Determines specific optical rotation using a polarimeter at 20 C and sodium D-line (589 nm) to confirm chiral integrity. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range of solid-to-liquid transition using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particles or discoloration against white/black background under controlled lighting. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by ignition at 700-800 C followed by weighing of residual residue. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution in dry powder form using laser scattering principles per ISO 13320. |
