Manufacturing Quality Control of m-Tolyldiethanolamine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Moisture Content | Karl Fischer Titration | Volumetric titration based on the reaction of water with iodine and sulfur dioxide in a methanol-pyridine medium. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Measurement of yellowness intensity by comparing sample absorbance at 430 nm to APHA color standards. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid transitions to liquid, indicating purity and identity. |
| Residue on Ignition | Gravimetric Analysis | Weighing of non-volatile inorganic residue remaining after high-temperature ashing at 700-800 C. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Atomic absorption measurement of total heavy metal content after acid digestion and calibration with lead standard. |
| Chloride Impurity | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode to detect endpoint via potential change. |
| Related Substances | HPLC-DAD | Separation and identification of structurally similar impurities using diode-array detection and retention time matching. |
| pH (1% aqueous solution) | pH Meter | Electrochemical measurement of hydrogen ion activity in a standardized aqueous solution at 25 C. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution to assess chiral purity. |
| Iron Content | ICP-OES | Elemental quantification by measuring characteristic atomic emission lines after microwave-assisted acid digestion. |
