Manufacturing Quality Control of 2-HYDROXY-4-NITRO-BENZALDEHYDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at ~330 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-DAD or HPLC-MS | Separation and identification of impurities (e.g., unreacted 2-hydroxybenzaldehyde, nitration by-products) via retention time and spectral matching. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content based on the stoichiometric reaction between iodine, sulfur dioxide, and water in pyridine/methanol medium. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Determination of inorganic ash content by ignition at 700–800 °C followed by weighing of residual inorganic matter. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification of heavy metals after acid digestion, based on element-specific atomic emission intensities. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride anions using suppressed conductivity detection after aqueous extraction. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement via controlled heating; sharp melting range indicates crystalline purity and absence of significant eutectic impurities. |
| Organic Volatile Impurities (e.g., DMF, toluene) | GC-FID | Headspace or direct injection GC analysis with flame ionization detection to quantify residual solvents per ICH Q3C guidelines. |
| Appearance and Color | Visual Inspection & APHA Color Scale | Subjective assessment of crystalline form and comparison of solution color against standardized APHA color scale (e.g., in ethanol). |
