Manufacturing Quality Control of 4-HYDROXY-3-METHYL-BENZOIC ACID METHYL ESTER
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-DAD | Separation and identification of impurities using HPLC coupled with diode array detection, with peak purity assessment and relative response factor correction. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify methanol, ethyl acetate, and other process solvents based on calibrated external standards. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification of heavy metals after acid digestion, using inductively coupled plasma optical emission spectrometry with matrix-matched calibration. |
| Chloride Content | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with suppressed conductivity detection and sodium carbonate/bicarbonate eluent. |
| Water Content | Karl Fischer Titration | Volumetric titration using iodine, sulfur dioxide, and pyridine in methanol medium; endpoint detected potentiometrically. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature at which solid phase completely transforms to liquid. |
| Appearance | Visual Inspection | Assessment under controlled white light against standard references for color, clarity, and presence of visible particles or discoloration. |
| Acid Value | Acid-Base Titration | Neutralization of free carboxylic acid groups with standardized potassium hydroxide ethanol solution using phenolphthalein indicator. |
| Sulfated Ash | Gravimetric Analysis | Incineration at 700-750 C followed by sulfuric acid treatment and final weighing of non-volatile residue. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as a function of angle to determine volume-based particle size distribution in dry dispersion mode. |
| Microbial Limits | Membrane Filtration | Quantitative recovery of viable aerobic microorganisms from sample solution via filtration, followed by incubation on soybean-casein digest agar. |
