Manufacturing Quality Control of (1S,2S)-(+)-1,2-Diaminocyclohexane
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component using retention time and peak area against certified reference standard. |
| Optical Rotation | [alpha]D measurement using polarimeter | Measures specific rotation at 20 C and 589 nm to confirm chiral integrity and enantiomeric purity. |
| Water Content | Karl Fischer Titration (coulometric or volumetric) | Determines trace water via iodine-sulfur dioxide redox reaction in anhydrous methanol-based medium. |
| Residue on Ignition | Gravimetric analysis after high-temperature ashing | Measures non-volatile inorganic impurities remaining after combustion at 700-800 C. |
| Heavy Metals | ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometry) | Simultaneously quantifies multiple metallic impurities (e.g., Pb, Cd, Hg, As) based on element-specific emission lines. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separates and quantifies chloride ions using anion-exchange column and suppressed conductivity detection. |
| Related Substances | HPLC with UV detection | Detects and quantifies structurally related impurities (e.g., mono-deaminated, oxidation products) using reversed-phase separation. |
| Acid Value | Acid-base titration with standardized NaOH solution | Determines free acidic impurities by neutralization with alcoholic KOH or NaOH and phenolphthalein endpoint. |
| Appearance | Visual inspection in clear glass container under controlled lighting | Assesses physical state, color, and clarity against water-white standard; detects particulates or phase separation. |
| Density | Oscillating U-tube densitometry | Measures mass per unit volume at 20 C using resonant frequency shift of a vibrating sample-filled tube. |
| Refractive Index | Refractometry at 20 C | Determines ratio of light velocity in air vs. sample using critical angle measurement with sodium D-line (589 nm). |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) with FID | Quantifies volatile organic solvents (e.g., methanol, dichloromethane) extracted into headspace and separated on capillary column. |
