Manufacturing Quality Control of 5,6,7,8-Tetrahydroquinolin-8-ol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time relative to reference standards or threshold limits. |
| Loss on Drying | Gravimetric Analysis | Measurement of mass loss after drying under controlled temperature and vacuum to determine volatile content including residual solvents and moisture. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify common organic solvents (e.g., methanol, acetone, ethyl acetate) against calibration curves. |
| Heavy Metals | ICP-OES | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma optical emission spectrometry. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode to determine chloride ion concentration based on potentiometric endpoint detection. |
| Sulfated Ash | Gravimetric Analysis | Determination of inorganic residue after combustion with sulfuric acid treatment and high-temperature ashing, followed by weighing. |
| Melting Point | Capillary Melting Point Apparatus | Thermal analysis using capillary tube method to observe solid-to-liquid transition range, indicating purity and identity. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line light to confirm chiral integrity and enantiomeric purity. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration with KF reagent to determine trace water content based on stoichiometric iodine-water reaction. |
| pH of Aqueous Solution | pH Meter | Electrochemical measurement of hydrogen ion activity in a defined aqueous suspension or solution to assess acidity/basicity profile. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as a function of angle to determine volume-based particle size distribution in dry or dispersed state. |
