Manufacturing Quality Control of 4-Methyl-benzoic acid tert-butyl ester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of impurities by retention time and UV absorbance relative to the main peak. |
| Residual Solvents | Gas Chromatography (GC) with Headspace sampling and FID detection | Headspace equilibration followed by GC separation and FID detection to quantify volatile organic solvents. |
| Moisture Content | Karl Fischer Titration (coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water in the sample. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Neutralization of free carboxylic acid groups using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Residue on Ignition | Gravimetric analysis after high-temperature ashing | Weight measurement of non-volatile inorganic residue remaining after combustion at 700-800 C in a muffle furnace. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after wet digestion | Quantification of total heavy metals by atomization and absorption measurement at characteristic wavelengths following acid digestion. |
| Chloride Content | Ion Chromatography (IC) or Potentiometric Titration | Separation and detection of chloride ions via conductivity (IC) or endpoint detection using silver nitrate titrant (titration). |
| Melting Point | Capillary Melting Point Determination | Thermal transition observed as the temperature range over which solid-to-liquid phase change occurs under controlled heating. |
| Appearance | Visual Inspection against standard white background | Subjective assessment of physical state, color, and presence of particulates or phase separation under controlled lighting. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral molecules in solution at specified concentration and path length. |
| Bulk Density | Graduated Cylinder Method (ASTM D1895) | Mass per unit volume determined by gently pouring material into a calibrated cylinder and measuring settled volume. |
