Manufacturing Quality Control of 3-acetyl-4-hydroxybenzoic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to calibrated standard. |
| Related Substances | HPLC-DAD | Identifies and quantifies impurities by retention time and UV spectral match against reference standards. |
| Residual Solvents | GC-FID | Measures volatile organic solvents using gas chromatography with flame ionization detection and external calibration. |
| Water Content | Karl Fischer Titration | Determines water via coulometric or volumetric titration using iodine generation in pyridine/methanol buffer. |
| Heavy Metals | ICP-OES | Quantifies metals (e.g., Pb, Cd, Hg, As) after acid digestion by measuring atomic emission intensities. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after controlled combustion with sulfuric acid treatment and high-temperature incineration. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary tube method. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light against standard reference. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Loss on Drying | Thermogravimetric Analysis | Determines volatile content by mass loss upon heating to 105 C under dry air or nitrogen for fixed duration. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light in solution to confirm chiral integrity and identity. |
