Manufacturing Quality Control of 13435-12-6
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies NMBA content by separation on a capillary column and flame ionization detection relative to an internal or external standard. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Determines trace water via electrochemical generation of iodine reacting stoichiometrically with water in anhydrous methanol-based reagent. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measures non-volatile inorganic impurities by weighing sample before and after high-temperature ashing at 500–600 °C. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Simultaneously quantifies trace heavy metals (e.g., Pb, Cd, Hg, As) after acid digestion using element-specific atomic emission lines. |
| Acidity (as Acetic Acid) | Acid-Base Titration with Potentiometric Endpoint | Neutralizes acidic impurities (e.g., residual acetic acid or silanols) using standardized NaOH solution; endpoint detected by pH electrode. |
| Chloride Content | Ion Chromatography (IC) with Conductivity Detection | Separates and quantifies chloride ions after aqueous extraction and filtration, using anion-exchange column and suppressed conductivity detection. |
| Appearance | Visual Inspection against Standard Reference | Assesses physical state, clarity, and color by observing undiluted sample in a clear glass container under controlled white light against established visual standards. |
| Density | Oscillating U-tube Densitometry | Measures mass per unit volume based on resonant frequency shift of a vibrating U-shaped tube filled with sample at controlled temperature (20 °C). |
| Refractive Index | Abbe Refractometry | Determines refractive index at 20 °C using sodium D-line (589 nm) by measuring angle of total internal reflection at prism-sample interface. |
| Volatile Impurities (e.g., Hexane, THF) | Gas Chromatography–Mass Spectrometry (GC-MS) | Identifies and quantifies low-boiling organic solvents by retention time and characteristic mass spectra following headspace or direct injection. |
| Residual Solvents (e.g., DMF, DCM) | Headspace Gas Chromatography (HS-GC) with FID | Quantifies regulated residual solvents after thermal equilibration in sealed vial, followed by GC separation and FID detection. |
| pH (10% w/v in Water) | pH Potentiometry | Measures hydrogen ion activity of aqueous suspension (hydrolyzed sample) using calibrated pH electrode; reflects hydrolytic stability and acidic/basic impurities. |
| Specific Rotation | Polarimetry | Determines optical rotation at 20 °C using sodium D-line to confirm chiral purity or detect enantiomeric impurities (though NMBA is achiral, used for batch consistency verification). |
