Manufacturing Quality Control of DL-TROPIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (DL-Tropinic Acid Content) | Acid-Base Titration with NaOH | Quantifies acidic functional group by neutralization with standardized sodium hydroxide solution using phenolphthalein or potentiometric endpoint detection. |
| Optical Rotation | [a]D Measurement | Determines specific optical rotation using a polarimeter to assess chiral purity and enantiomeric composition. |
| Water Content | Karl Fischer Titration | Measures trace water via iodine-sulfur dioxide redox reaction in anhydrous methanol-based reagent. |
| Residue on Ignition | Gravimetric Analysis | Evaluates inorganic impurities by ignition at 700-800 C and weighing the non-volatile residue. |
| Heavy Metals | ICP-OES | Simultaneously quantifies Pb, Cd, Hg, As, and other heavy metals after acid digestion using plasma emission spectroscopy. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions based on anion exchange retention and conductivity detection. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 under controlled pH and temperature, followed by filtration and weighing. |
| Related Substances | HPLC with UV Detection | Separates and quantifies structurally related impurities using reversed-phase chromatography and UV absorbance at 210 nm. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity in a 1% w/v aqueous solution using calibrated glass electrode. |
| Solvent Residues | Gas Chromatography (GC-FID) | Detects and quantifies residual solvents (e.g., methanol, acetone, ethyl acetate) using flame ionization detection. |
| Microbial Contamination | Membrane Filtration and Plate Count | Assesses aerobic microbial load by filtration, membrane transfer to agar media, and colony enumeration after incubation. |
