Manufacturing Quality Control of 617-33-4
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area comparison against certified reference standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Acidity (as HBr) | Acid-Base Titration with NaOH | Neutralizes acidic impurities (e.g., HBr, bromoacetic acid) using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color | Visual Comparison Against APHA Scale | Compares sample color in solution to standardized platinum-cobalt color scale under controlled lighting. |
| Density at 20 degC | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle calibrated with air and water standards. |
| Refractive Index at 20 degC | Abbe Refractometer | Measures bending of light through liquid sample to determine refractive index correlated with purity and composition. |
| Residue on Evaporation | Gravimetric Analysis | Evaporates known volume at controlled temperature and weighs non-volatile residue after drying. |
| Heavy Metals (as Pb) | ICP-OES | Quantifies trace metal contaminants by plasma excitation and elemental emission wavelength detection. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using ion-exchange column and conductivity detection. |
| Ethyl Bromoacetate (Related Substance) | Gas Chromatography (GC) with FID | Identifies and quantifies structurally related ester impurity by relative retention time and response factor. |
| Bromoacetic Acid (Related Substance) | HPLC with UV Detection | Separates and quantifies acidic impurity using reversed-phase column and UV absorbance at 210 nm. |
| Non-Volatile Residue | Gravimetric Analysis | Heats sample to dryness, cools in desiccator, and weighs residual solids after solvent evaporation. |
