Manufacturing Quality Control of 5-HYDROXY-2-METHYL-BENZOIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC with UV detection; identification based on retention time matching and relative response factors. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify common organic solvents (e.g., methanol, acetone, toluene) based on calibrated external standards. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element determination of heavy metals after acid digestion; detection based on atomic emission intensities at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation of chloride anions on anion-exchange column with suppressed conductivity detection; quantified against sodium chloride calibration standards. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample at 700-800 C followed by weighing of residual inorganic ash after sulfuric acid treatment. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent; water reacts stoichiometrically with iodine, sulfur dioxide, and base in methanol medium. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, observed visually under controlled heating rate per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles against defined reference standards under controlled lighting. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measurement of hydrogen ion activity in a 1% w/v aqueous suspension using calibrated glass electrode and pH meter. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as a function of angle to determine volume-based particle size distribution in dispersed powder sample. |
| Bulk Density | ASTM D1895 | Determination of mass per unit volume for freely settled powder using standardized graduated cylinder and balance per ASTM D1895 Method A. |
