Manufacturing Quality Control of 2-(4-Methylphenyl)propanoic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC with UV detection | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV absorbance at 254 nm. |
| Related Substances | HPLC with UV detection | Separation and quantification of structurally related impurities (e.g., toluene, p-tolualdehyde, p-cresol) using gradient elution and UV detection. |
| Residual Solvents | Gas Chromatography (GC) with FID | Separation and quantification of volatile organic solvents (e.g., methanol, toluene, ethyl acetate) by capillary GC and flame ionization detection. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to quantify water content based on the stoichiometric reaction with water. |
| Heavy Metals | ICP-OES | Multi-element quantification of heavy metals (e.g., Pb, Cd, As, Hg) after acid digestion, using plasma excitation and optical emission detection. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride ions using anion-exchange column and suppressed conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Determination of inorganic residue after controlled incineration at 700-800 C, followed by weighing of the residual ash. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement by observing the temperature range at which solid-to-liquid phase change occurs under controlled heating. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of the sample against defined standards under controlled lighting conditions. |
| Acid Value | Acid-Base Titration | Neutralization of carboxylic acid groups with standardized potassium hydroxide solution using phenolphthalein indicator. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral molecules in solution at specified concentration and path length. |
