Manufacturing Quality Control of Cholesteryl benzoate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 205-220 nm, comparing peak area against a certified reference standard. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, following USP <741> or ISO 6383-1. |
| Loss on Drying | Gravimetric (Oven Drying) | Measurement of mass loss after drying at 105 C for 2 hours under atmospheric pressure. |
| Residue on Ignition | Sulfated Ash Gravimetry | Ignition of sample at 600-700 C followed by weighing of inorganic residue after sulfuric acid treatment. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Quantification of total heavy metals by atomic absorption spectroscopy after wet ashing and acid digestion. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride ions using anion-exchange column with conductivity detection. |
| Sulfate Impurity | Turbidimetric Method | Formation of barium sulfate precipitate in acidic medium, measured by light scattering at 420 nm. |
| Related Substances | HPLC-DAD | Identification and quantification of structurally related impurities using gradient HPLC with diode-array detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on the stoichiometric reaction of iodine with water in pyridine-methanol medium. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light at 20 C using sodium D-line (589 nm) in chloroform solution. |
| Acid Value | Acid-Base Titration | Titration with standardized potassium hydroxide solution to neutralize free carboxylic acids, expressed as mg KOH/g. |
| Residual Solvents | GC-FID | Quantitative analysis of volatile organic solvents using gas chromatography with flame ionization detection and internal standard calibration. |
