Manufacturing Quality Control of DIMETHYL TRANS-1,4-CYCLOHEXANEDICARBOXYLATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 210 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., cis-isomer, mono-ester, diacid) using gradient HPLC-UV against qualified impurity standards. |
| cis-Isomer Content | GC-FID | Gas chromatographic separation on a chiral or polar capillary column with flame ionization detection; relative response calibrated with cis-isomer reference. |
| Residual Solvents | GC-FID | Headspace GC-FID analysis for common solvents (e.g., methanol, toluene, ethyl acetate) per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent; water reacts stoichiometrically with iodine and sulfur dioxide in pyridine/methanol medium. |
| Acid Value | Acid-Base Titration | Titration with standardized potassium hydroxide solution in ethanol/isopropanol; endpoint detected potentiometrically or by phenolphthalein. |
| Heavy Metals | ICP-OES | Digestion followed by multi-element quantification using inductively coupled plasma optical emission spectroscopy; detection limits compliant with ICH Q3D. |
| Residue on Ignition | Gravimetric Analysis | Ignition at 700-800 C to constant weight; inorganic residue measured as percentage of original sample mass. |
| Appearance | Visual Inspection | Comparison of sample solution (in specified solvent) against water or reference standard under controlled white light and defined viewing conditions. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as the temperature range over which solid-to-liquid phase change occurs, using calibrated digital melting point instrument. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light at 20 C using sodium D-line (589 nm); reported as degrees per dm·g/mL. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity vs. angle to determine volume-based particle size distribution in dispersed slurry. |
