Manufacturing Quality Control of (1R,2R)-(-)-1,2-Diaminocyclohexane
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Chemical Purity | High-Performance Liquid Chromatography (HPLC) | Utilizes reversed-phase or normal-phase chromatographic columns with UV detection (e.g., 210 nm) to quantify the main component and assess impurity levels. The mobile phase typically consists of a buffer-salt–organic solvent system. |
| Enantiomeric Purity (Optical Purity) | Chiral High-Performance Liquid Chromatography (Chiral HPLC) | Separates enantiomers using chiral stationary phase columns; enantiomeric excess (ee value) is calculated from peak areas to ensure the L-isomer predominates. |
| Moisture Content | Karl Fischer Titration | Determines trace moisture in samples using coulometric or volumetric methods, ensuring compliance with drying loss or moisture content specifications (e.g., ≤0.5%). |
| Residual Solvents | Gas Chromatography (GC) | Uses headspace or direct injection with capillary columns and FID detection to quantify common organic solvent residues (e.g., methanol, ethanol, ethyl acetate). |
| Melting Point | Capillary Melting Point Determination | Determined using a digital melting point apparatus to measure the melting temperature range, verifying crystal structure consistency (literature value approximately ~104–106°C). |
| Specific Rotation | Polarimetry Measurement | Measures specific rotation [α] at a specified wavelength (typically 589 nm, sodium D-line) and concentration to confirm the levorotatory configuration (literature value approximately -50° to -60°). |
| Appearance and Color | Visual Inspection | White to off-white crystalline powder, free of visible foreign matter or discoloration, meeting pharmacopoeial or internal company specifications. |
| pH (Solution) | pH Meter Measurement | Prepared as a solution of defined concentration (e.g., 1% w/v), pH measured to assess acidity/alkalinity within the specified range (typically slightly alkaline). |
| Residue on Ignition / Ash Content | Gravimetric Method | Sample is ignited at high temperature (e.g., 700–800°C), and the residual ash is weighed to assess inorganic impurities (generally required ≤0.1%). |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, limits of lead, arsenic, mercury, cadmium, and other trace elements are determined, complying with ICH Q3D or pharmacopoeial heavy metal limits. |
