Manufacturing Quality Control of 832-53-1
| 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. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration where iodine is generated coulometrically to react stoichiometrically with water in the sample. |
| Residual Solvents | Gas Chromatography (GC) with Headspace sampling | Separation and quantification of volatile organic impurities using headspace equilibrium followed by GC-FID or GC-MS detection. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of acidic impurities (e.g., sulfonic acids, HCl) using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Chloride Ion Impurity | Ion Chromatography (IC) | Separation of anions on an ion-exchange column with conductivity detection; chloride quantified via calibration curve. |
| Heavy Metals (Pb, Cd, Hg, As) | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Atomization and ionization in plasma followed by mass-selective detection at trace levels after acid digestion. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against a white background under controlled lighting conditions. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature using calibrated digital apparatus per USP <741>. |
| Sulfonic Acid Impurity | High Performance Liquid Chromatography (HPLC) with UV detection | Separation on reversed-phase C18 column and quantification of sulfonic acid derivatives at 254 nm. |
| Non-Volatile Residue | Gravimetric Analysis (Weight Loss on Drying) | Evaporation of volatile components at 105 C, followed by weighing of residual solids after cooling in desiccator. |
| Organic Volatile Impurities (other than solvents) | GC-MS | Identification and semi-quantification of unknown volatile/semi-volatile organic impurities using mass spectral library matching. |
| Particle Size Distribution | Laser Diffraction | Measurement of scattered light intensity as function of angle to calculate volume-based particle size distribution in dispersed slurry. |
