| Pharmaceuticals | Excipient, solvent | Produced via enzymatic esterification or chemical synthesis |
Manufacturing Quality Control of GLYCERYL DIOLEATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Acid Value | Acid-Base Titration | Neutralization of free fatty acids with standardized KOH solution using phenolphthalein indicator. |
| Iodine Value | Wijs Method | Addition of excess iodine monochloride to double bonds, followed by titration of unreacted iodine with sodium thiosulfate. |
| Saponification Value | Acid-Base Titration | Complete hydrolysis with excess KOH, followed by back-titration of unreacted alkali with HCl. |
| Peroxide Value | Iodometric Titration | Oxidation of potassium iodide by peroxides to liberate iodine, titrated with sodium thiosulfate. |
| Refractive Index | Refractometry | Measurement of light bending angle at air-sample interface using calibrated refractometer at specified temperature. |
| Color (Gardner Scale) | Visual Comparison or Spectrophotometry | Comparison of sample color against standard Gardner liquid color scales or measurement at 455 nm. |
| Moisture Content | Karl Fischer Titration | Quantitative reaction of water with iodine and sulfur dioxide in pyridine/methanol medium, monitored electrometrically. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Atomization of sample followed by measurement of absorption of characteristic wavelength radiation by ground-state metal atoms. |
| Residual Solvents (e.g., hexane) | Gas Chromatography (GC) | Separation and quantification of volatile solvents based on retention time and peak area using flame ionization detection. |
| Fatty Acid Composition | Gas Chromatography with Flame Ionization Detection (GC-FID) | Derivatization to methyl esters followed by separation on polar capillary column and quantification via response factors. |
| Unsaponifiable Matter | Solvent Extraction and Gravimetry | Extraction of non-saponifiable components with diethyl ether after saponification, followed by solvent evaporation and weighing. |
| Total Glycidyl Esters | Gas Chromatography-Mass Spectrometry (GC-MS) | Derivatization with phenylboronic acid, separation by GC, and selective detection/quantification using mass spectrometry. |
