Manufacturing Quality Control of 2-(TERT-BUTYL)PHENYL ISOCYANATE
| 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. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile organic impurities are vaporized in sealed vials and quantified by GC-FID or GC-MS against calibrated standards. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Acid Number | Acid-Base Titration (NaOH in methanol) | Neutralization of acidic impurities (e.g., residual HCl, carboxylic acids) with standardized sodium hydroxide solution using phenolphthalein or potentiometric endpoint. |
| Chloride Content | Ion Chromatography (IC) | Separation of chloride anions on an anion-exchange column followed by conductivity detection and quantification against calibration standards. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element detection after acid digestion; isotopic mass spectrometry provides ultra-trace quantification based on element-specific mass-to-charge ratios. |
| Color (APHA) | Visual Comparison or Spectrophotometry at 455 nm | Measurement of yellowness intensity by comparing sample absorbance at 455 nm to platinum-cobalt standards or APHA scale. |
| Density at 20 C | Digital Density Meter (Oscillating U-tube) | Determination via precise measurement of oscillation period of a U-shaped glass tube filled with sample, correlated to density using calibration standards. |
| Refractive Index at 20 C | Digital Refractometer | Measurement of light refraction angle at specified wavelength (typically 589 nm) to determine refractive index as a function of molecular composition and purity. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash) | Sample is charred, sulfated with H2SO4, and ignited at 700-750 C; residue weight reflects inorganic impurities. |
| Free Isocyanic Acid (NCO content) | Dibutylamine Back-Titration | Reaction of NCO groups with excess dibutylamine, followed by titration of unreacted amine with HCl to calculate NCO wt%. |
| Related Substances (Impurities) | HPLC with UV Detection | Separation on reversed-phase C18 column; detection at 220–254 nm; identification and quantification relative to main peak using reference standards or area normalization. |
