Manufacturing Quality Control of 4-Isopropylbenzoic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC with UV detection | Quantitative determination based on peak area comparison against a certified reference standard using reversed-phase chromatography. |
| Melting Point | Capillary melting point apparatus | Measurement of temperature range at which solid transitions to liquid, indicating purity and identity. |
| Loss on Drying | Gravimetric method (oven drying) | Mass loss measured after heating sample at specified temperature to remove volatile impurities and moisture. |
| Residue on Ignition | Sulfated ash gravimetric method | Non-volatile inorganic residue determined after high-temperature combustion and sulfuric acid treatment. |
| Chloride Impurity | Ion chromatography (IC) | Separation and quantification of chloride ions using anion-exchange column and conductivity detection. |
| Sulfate Impurity | Ion chromatography (IC) | Separation and quantification of sulfate ions using anion-exchange column and conductivity detection. |
| Heavy Metals (as Pb) | Atomic absorption spectroscopy (AAS) | Quantification of total heavy metals after wet digestion, using lead as the reference element and flame or graphite furnace AAS. |
| Related Substances | HPLC with diode array detection | Identification and quantification of structurally related impurities by retention time and spectral comparison. |
| Water Content | Karl Fischer titration | Volumetric or coulometric titration based on iodine-sulfur dioxide reaction specific for water. |
| Appearance | Visual inspection | Assessment of physical state, color, and clarity against established reference standards under controlled lighting. |
| pH of Aqueous Suspension | pH meter measurement | Determination of acidity/basicity of a standardized suspension in water or water-ethanol mixture. |
| Iron Impurity | Inductively coupled plasma optical emission spectrometry (ICP-OES) | Multi-element trace metal analysis after acid digestion, using iron-specific emission wavelength. |
