Manufacturing Quality Control of 502-47-6
| 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 under validated chromatographic conditions. |
| Appearance | Visual Inspection | Assessment of liquid clarity and color against water-white standard under controlled lighting conditions. |
| Acid Value | Acid-Base Titration (KOH in ethanol/isopropanol) | Neutralization of free carboxylic acid groups with standardized potassium hydroxide solution, using phenolphthalein or potentiometric endpoint detection. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical quantification of water via iodine generation and stoichiometric reaction with water in anhydrous methanol-based reagent. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measurement of non-volatile inorganic residue after controlled high-temperature ashing (500–600 °C) of a weighed sample. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Multi-element quantitative analysis based on element-specific atomic emission intensities following acid digestion and nebulization. |
| Refractive Index | Refractometry (at 20 °C) | Measurement of light bending angle through the neat liquid sample at specified temperature, correlated to molecular composition and purity. |
| Specific Gravity | Digital Density Meter (Oscillating U-tube) | Determination of mass per unit volume by measuring resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Odor | Sensory Evaluation (Qualified Panel) | Organoleptic assessment by trained personnel for characteristic odor profile and absence of off-odors, per USP <1093> guidelines. |
| Non-Volatile Residue | Evaporation Residue Test (Gravimetric) | Quantification of residue remaining after gentle evaporation of a fixed sample volume under nitrogen stream and drying to constant weight. |
| Related Substances | Gas Chromatography–Mass Spectrometry (GC-MS) | Identification and semi-quantitation of structurally related impurities (e.g., isomers, oxidation products) using retention time and spectral matching. |
| Optical Rotation | Polarimetry (at 20 °C, sodium D-line) | Measurement of angular rotation of plane-polarized light induced by chiral centers in solution, indicating enantiomeric composition. |
| Flash Point | Closed-Cup Pensky-Martens Tester | Determination of lowest temperature at which vapors ignite momentarily under standardized heating and ignition conditions (ASTM D93). |
