Manufacturing Quality Control of 5-Isoquinolinesulfonic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at ~254 nm. |
| Loss on Drying (LOD) | Gravimetric Thermogravimetry | Measurement of mass loss after drying under controlled temperature and vacuum or nitrogen purge, reflecting volatile content including residual solvents and water. |
| Residual Solvents | GC-FID | Separation and quantification of common organic solvents (e.g., methanol, acetone, DMF) by gas chromatography with flame ionization detection using a polar capillary column. |
| Heavy Metals (as Pb) | ICP-MS | Multi-element trace metal quantification via inductively coupled plasma mass spectrometry after acid digestion, offering sub-ppt detection limits for toxic elements. |
| Sulfate Impurity | Ion Chromatography (IC) | Anion-selective separation and conductivity detection of sulfate ions, distinguishing from the sulfonic acid functional group of the analyte. |
| Related Substances | HPLC-DAD | Identification and quantification of structurally similar impurities (e.g., isomers, desulfo analogs) using diode-array detection for spectral confirmation and peak purity assessment. |
