Manufacturing Quality Control of ETHYL 5-NORBORNENE-2-CARBOXYLATE (MIXTURE OF ENDO AND EXO)
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area comparison against certified reference standard. |
| Related Substances | Gas Chromatography (GC) with FID or MS detection | Separates and detects impurities based on volatility and retention behavior relative to main compound. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in anhydrous methanol/pyridine medium. |
| Acid Value | Acid-Base Titration with NaOH | Determines free carboxylic acid content by neutralizing with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measures non-volatile inorganic residue after high-temperature ashing at 700-800 C. |
| Heavy Metals | ICP-OES | Quantifies trace metal contaminants (e.g., Pb, Cd, Hg, As) by atomic emission intensity of ionized elements in plasma. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions based on anion exchange retention and conductivity detection. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light caused by chiral centers in the molecule at specified wavelength and temperature. |
| Refractive Index | Refractometry | Determines ratio of light velocity in air vs. sample at 20 C using calibrated refractometer. |
| Density | Oscillating U-tube Densitometry | Measures mass per unit volume via resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against established reference standards under controlled lighting. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Detects and quantifies volatile organic solvents (e.g., ethanol, ethyl acetate) by equilibrium vapor phase analysis. |
