Manufacturing Quality Control of 4-(dimethylamino)benzenesulphonic acid

Detection Item Common Analytical Method Method Overview
Assay (Purity) Acid-Base Titration Quantifies active compound by titration with standardized NaOH using phenolphthalein indicator.
Moisture Content Karl Fischer Titration Measures water content via iodometric reaction with Karl Fischer reagent.
Residue on Ignition Gravimetric Analysis Determines inorganic ash content by high-temperature incineration and weight measurement.
Heavy Metals ICP-OES Quantifies trace metal impurities (e.g., Pb, Cd, Hg) by atomic emission spectroscopy after acid digestion.
Chloride Impurity Potentiometric Titration Detects chloride ions using silver nitrate titration with silver electrode detection.
Sulfate Impurity Barium Sulfate Gravimetry Precipitates sulfate as BaSO4 and determines mass after filtration and drying.
Related Substances HPLC-UV Separates and quantifies structurally related impurities using reversed-phase chromatography and UV detection.
Melting Point Capillary Melting Point Apparatus Determines temperature range at which solid transitions to liquid using calibrated capillary method.
Color Visual Comparison (APHA Scale) Compares solution color against platinum-cobalt standards in accordance with APHA 10520.
Solubility in Water Qualitative Dissolution Test Evaluates complete dissolution in specified volume of water at defined temperature and time.
pH of Aqueous Solution pH Meter Measurement Measures hydrogen ion activity of a standardized aqueous suspension using calibrated pH electrode.
Organic Volatile Impurities GC-FID Detects residual solvents by gas chromatographic separation followed by flame ionization detection.
