Manufacturing Quality Control of 1-Naphthyl isocyanate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC with UV detection | Quantitative determination using reverse-phase HPLC and UV absorbance at 254 nm, calibrated against certified reference standard. |
| Appearance | Visual inspection | Assessment of physical state and clarity in a clean, colorless glass container under controlled lighting. |
| Color (APHA) | Spectrophotometric colorimetry | Measurement of yellowness index by comparing sample absorbance to APHA platinum-cobalt standard solutions at 430 nm. |
| Moisture content | Karl Fischer titration | Electrochemical titration using iodine generation to quantify water based on stoichiometric reaction with Karl Fischer reagent. |
| Acid number | Acid-base titration | Neutralization of acidic impurities with standardized KOH solution in isopropanol/toluene mixture, using phenolphthalein indicator. |
| Residue on ignition | Gravimetric analysis | Heating sample at 750 C to constant weight and measuring non-volatile inorganic residue as percent mass loss. |
| Heavy metals (as Pb) | ICP-OES | Multi-element quantification after acid digestion, based on characteristic atomic emission intensities in argon plasma. |
| Chloride content | Potentiometric titration | Titration with silver nitrate using silver electrode to detect endpoint via potential change from AgCl precipitation. |
| Melting point | Capillary melting point apparatus | Determination of solid-to-liquid transition temperature range using calibrated capillary tube method per USP <741>. |
| Density at 20 C | Oscillating U-tube densitometry | Measurement of sample density via resonant frequency shift of a vibrating U-shaped glass tube filled with sample. |
| Refractive index at 20 C | Refractometry | Determination of light bending angle at air-sample interface using sodium D-line (589 nm) per ASTM D1218. |
| Volatile impurities | Gas chromatography (GC-FID) | Separation and quantification of low-boiling organic impurities using capillary column and flame ionization detection. |
