Manufacturing Quality Control of N-Isopropylphthalimide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at ~220–254 nm, comparing peak area against a certified reference standard. |
| Loss on Drying (LOD) | Gravimetric Thermogravimetry | Measurement of mass loss after drying at 105 °C under vacuum or nitrogen until constant weight is achieved. |
| Residue on Ignition (Sulfated Ash) | Gravimetric Sulfated Ash Test | Sample charred, treated with sulfuric acid, and ignited at 700–800 °C; residual inorganic ash is weighed. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, using plasma emission spectroscopy. |
| Chloride Impurity | Potentiometric Titration with AgNO₃ | Titration with standardized silver nitrate solution using a silver indicator electrode; endpoint detected by potential jump. |
| Related Substances | HPLC-DAD | Separation and identification of structurally similar impurities (e.g., phthalic anhydride, isopropylamine) using HPLC with diode-array detection. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, using calibrated capillary apparatus per USP <741>. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemical titration measuring water via iodine generation; stoichiometric reaction with water in anhydrous methanol-based solvent. |
| Appearance (Color & Clarity) | Visual Inspection in Standardized Glass Cell | Assessment of physical state, color (vs. APHA scale), and clarity against specified criteria in transparent glass container under controlled lighting. |
| Specific Optical Rotation | [α]D | Measurement of rotation angle of plane-polarized light at 589 nm using sodium D-line; indicates chiral purity (if applicable) and identity confirmation. |
| Residual Solvents (e.g., Acetone, IPA) | GC-FID | Quantitative analysis of volatile organic solvents using gas chromatography with flame ionization detection and internal standard calibration. |
| pH of Aqueous Suspension | pH Meter Measurement | Determination of pH in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode per USP <791>. |
