Manufacturing Quality Control of 3,5-Di-tert-butyl-4-hydroxybenzoic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 280 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification by retention time matching and peak area normalization. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid phase transition temperature using calibrated capillary apparatus under controlled heating rate. |
| Loss on Drying | Gravimetric (105 C, 2 h) | Mass loss measured after drying sample at 105 C for 2 hours; reflects volatile content including residual solvents and moisture. |
| Residue on Ignition | Gravimetric (Sulfated Ash) | Mass of inorganic residue remaining after high-temperature incineration (700-800 C) following sulfuric acid treatment. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Quantification of total heavy metals by atomic absorption spectroscopy after acid digestion and matrix-matched calibration. |
| Chloride Content | Potentiometric Titration with AgNO3 | Titration with silver nitrate using silver indicator electrode; endpoint detected by potential inflection corresponding to AgCl precipitation. |
| Sulfated Ash | Gravimetric (700 C, 30 min) | Mass of non-volatile inorganic residue after ignition at 700 C for 30 minutes without prior sulfation. |
| pH of Aqueous Suspension (1% w/v) | pH Meter | Measurement of hydrogen ion activity in a saturated aqueous suspension using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to determine volume-based particle size distribution in dispersed powder sample. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration with iodine-based reagent; based on stoichiometric reaction between iodine and water. |
| Organic Volatile Impurities (e.g., toluene, MTBE) | GC-FID | Separation and quantification of residual solvents using gas chromatography with flame ionization detection and external calibration. |
