Manufacturing Quality Control of (R)-(+)-Indoline-2-carboxylic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC with Chiral Column | Enantioselective separation and quantification using a chiral stationary phase and UV detection at ~220 nm. |
| Chiral Purity (enantiomeric excess, ee) | Chiral HPLC or SFC | Separation of (R)- and (S)-enantiomers via chiral chromatography; ee calculated from peak area ratio. |
| Residual Solvents | GC-FID or GC-MS | Quantitative determination of volatile organic solvents (e.g., methanol, ethyl acetate) using headspace-GC with flame ionization or mass spectrometric detection. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element trace metal quantification after acid digestion, based on elemental mass-to-charge ratio detection. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration measuring water via iodine generation and stoichiometric reaction with water in anhydrous medium. |
| Residue on Ignition (Sulfated Ash) | Gravimetric Analysis | Incineration at 700–800 °C followed by weighing of non-volatile inorganic residue. |
| Optical Rotation | [α]D Measurement | Determination of specific rotation using a polarimeter at 20 °C with sodium D-line (589 nm) to confirm chiral identity and enantiomeric integrity. |
| Related Substances (Impurities) | HPLC with UV Detection | Separation and quantification of structurally related impurities (e.g., (S)-enantiomer, decarboxylated or hydrolyzed by-products) using reversed-phase C18 column. |
| pH (of aqueous suspension) | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) to assess acidic character and potential degradation. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample via light scattering to determine D10, D50, D90 values for bulk handling and formulation suitability. |
