Manufacturing Quality Control of 2,3-Dimethylbenzonitrile
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against certified reference standard using a non-polar capillary column. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated coulometrically reacts stoichiometrically with water in the sample. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Sample is ignited at 700–800 °C; residual inorganic ash is weighed after cooling in a desiccator. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after acid digestion | Sample digested with nitric acid/hydrogen peroxide; lead concentration measured by absorbance at 283.3 nm. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separation of chloride anions on an anion-exchange column followed by quantitative detection via suppressed conductivity. |
| Acid-Value | Acid-Base Titration (NaOH, phenolphthalein indicator) | Neutralization of acidic impurities (e.g., benzoic acid) with standardized sodium hydroxide solution. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Measurement of yellowness intensity relative to platinum-cobalt standards or absorbance at 455 nm in a 10-mm cell. |
| Residual Solvents (e.g., toluene, methanol) | Headspace Gas Chromatography (HS-GC) with FID | Volatile solvents partitioned into headspace and quantified by GC-FID against calibration standards. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid phase transition temperature range using calibrated digital melting point instrument. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution of known concentration and path length. |
| Related Substances (Impurity Profile) | High-Performance Liquid Chromatography (HPLC) with UV detection | Separation on reversed-phase C18 column; detection at 220 nm; identification/quantification against reference impurities. |
| Sulfated Ash | Gravimetric Analysis (Sulfuric Acid Digestion) | Sample carbonized, treated with sulfuric acid, ignited at 600 °C; residual sulfate ash is weighed. |
| Refractive Index | Digital Refractometer at 20 °C | Measurement of ratio of speed of light in air vs. sample liquid at specified temperature and wavelength (589 nm). |
