Manufacturing Quality Control of 5,6,7,8-Tetrahydro-2-naphthol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibration curve using internal or external standard. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies impurities based on retention time and mass spectral fragmentation patterns. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemically determines water via iodine generation and stoichiometric reaction with water in anhydrous medium. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing of sample. |
| Heavy Metals | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Detects trace metal elements by measuring characteristic atomic emission wavelengths after plasma atomization. |
| Chloride Content | Potentiometric Titration with AgNO3 | Determines chloride ions by titration with silver nitrate, monitored via silver ion-selective electrode endpoint. |
| Acidity (as H2SO4) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution with phenolphthalein indicator. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid, indicating crystallinity and purity. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of particulates or phase separation against established reference standards. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light by chiral compounds; used to confirm stereochemical integrity if relevant. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying | Determines volatile content by mass loss upon controlled heating under specified conditions. |
| pH of Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in saturated aqueous suspension using calibrated pH electrode. |
