Manufacturing Quality Control of 3,4-DIHYDROXYBENZAMIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at ~280 nm, comparing peak area against a certified reference standard. |
| Water Content | Karl Fischer Titration | Electrochemical titration based on the stoichiometric reaction of iodine with water in a pyridine/methanol solvent system. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 750–800 °C to volatilize organic matter; residual inorganic ash is weighed. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification 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 eluent separation. |
| Related Substances | HPLC-DAD | Identification and quantification of structurally similar impurities (e.g., 3-hydroxybenzonitrile, catechol) using diode-array detection and retention time matching. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change under controlled heating rate, per USP <741>. |
| Residual Solvents (e.g., methanol, acetone) | GC-FID | Separation by gas chromatography followed by flame ionization detection, calibrated against solvent standards. |
| Appearance (Color & Clarity) | Visual Inspection | Assessment against water-white standard in a clear glass container under controlled daylight illumination per EP 2.2.1. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined saturated aqueous suspension (e.g., 1% w/v) using a calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns to determine volumetric particle size distribution. |
| Sulfated Ash | Gravimetric Analysis | Ignition after sulfuric acid treatment to convert metals to stable sulfates; residue is weighed. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral molecules in solution, per USP <781>. |
