Manufacturing Quality Control of 3-METHYLHIPPURIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-DAD | Separation and identification of impurities by retention time and UV spectral matching; detection and quantification using diode array detection. |
| Residual Solvents | GC-FID | Volatile organic solvents are separated by capillary GC and quantified via flame ionization detection using external calibration standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration where iodine reacts stoichiometrically with water in a pyridine-methanol solvent system. |
| Heavy Metals | ICP-OES | Multi-element quantification of metals (e.g., Pb, Cd, Hg, As) after acid digestion, based on atomic emission intensity at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation of chloride anions on an anion-exchange column with suppressed conductivity detection and quantification against chloride standards. |
| Sulfated Ash | Gravimetric Analysis | Sample incineration at 700-800 C followed by sulfuric acid treatment and final ash weight measurement as inorganic residue. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid-to-liquid phase transition occurs, using calibrated capillary tube method per USP <741>. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral molecules in solution at specified concentration and wavelength (e.g., 589 nm). |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns to calculate volume-based particle size distribution in dry or wet dispersion. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination of hydrogen ion activity using calibrated glass electrode and reference electrode in a 1% w/v aqueous suspension. |
| Microbial Contamination | Membrane Filtration | Quantitative recovery of viable aerobic microorganisms from sample solution by filtration, followed by incubation on soybean-casein digest agar. |
