Manufacturing Quality Control of 2-BROMOPHENYL ISOCYANATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against certified reference standard under optimized chromatographic conditions. |
| Residual Solvents | Gas Chromatography (GC) with Headspace sampling | Volatile organic impurities are vaporized in headspace vial and quantified by GC-FID using external calibration. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated coulometrically reacts stoichiometrically with water in the sample. |
| Acid Value | Acid-Base Titration (NaOH in methanol) | Neutralization of acidic impurities (e.g., HBr, carboxylic acids) with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Comparison of sample color intensity to platinum-cobalt standard solutions at 455 nm wavelength. |
| Density | Digital Density Meter (Oscillating U-tube principle) | Measurement of sample density based on resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index | Refractometry (Abbe refractometer) | Determination of refractive index by measuring critical angle of total internal reflection at prism-sample interface. |
| Chloride Impurity | Ion Chromatography (IC) with Conductivity Detection | Separation of chloride anions on anion-exchange column followed by quantitative detection via conductivity measurement. |
| Heavy Metals (Pb, Cd, Hg, As) | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Atomization, ionization, and mass-selective detection of trace metal elements after acid digestion. |
| Residual Bromine (as Br2 or HBr) | Redox Titration (Sodium Thiosulfate with KI starch indicator) | Oxidizing bromine species liberate iodine from potassium iodide; liberated iodine is titrated with standardized thiosulfate. |
| Non-Volatile Residue | Gravimetric Analysis (Evaporation and Weighing) | Sample is evaporated to dryness at controlled temperature and residue mass is determined by precision weighing. |
| Appearance (Clarity and State) | Visual Inspection (against white/black background) | Assessment of physical state, clarity, and presence of suspended particles or phase separation under controlled lighting. |
