Manufacturing Quality Control of (S)-2-Methyl-pyrrolidine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard under validated chromatographic conditions. |
| Optical Rotation | [alpha]D Measurement using Polarimeter | Measures the angle of rotation of plane-polarized light caused by chiral molecules in solution at specified concentration, temperature, and wavelength. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Residue on Ignition | Gravimetric Analysis after Ignition | Sample is ignited at 700-800 C to oxidize organic matter; inorganic residue is weighed as percentage of original sample. |
| Heavy Metals | ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometry) | Multi-element detection based on characteristic atomic emission lines following acid digestion and plasma atomization/excitation. |
| Chloride Impurity | Ion Chromatography (IC) with Conductivity Detection | Separation of anions on ion-exchange column followed by quantitative detection via changes in solution conductivity. |
| Related Substances | GC-MS or UHPLC-MS | Separation followed by mass spectral identification and semi-quantitative estimation of structurally related impurities using reference standards or relative response factors. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution with phenolphthalein or potentiometric endpoint detection. |
| Appearance | Visual Inspection in Clear Glass Container | Assessment of physical state, color, and clarity against water-white standard under controlled lighting and viewing conditions. |
| Density | Oscillating U-tube Densitometry | Measures density based on resonant frequency shift of a vibrating U-shaped tube filled with sample at controlled temperature. |
| Refractive Index | Abbe Refractometry | Determines refractive index by measuring critical angle of total internal reflection at prism-sample interface at 20 C. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) with FID | Quantifies volatile organic solvents via equilibrium partitioning into headspace followed by GC separation and flame ionization detection. |
