Manufacturing Quality Control of 2-hydroxypropane-1,3-diyl diacetate
| 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. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration based on iodine-sulfur dioxide redox reaction. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Determines free acid content by neutralization with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Evaluates yellowness by comparing sample color to APHA platinum-cobalt standards or measuring absorbance at 430 nm. |
| Density at 20 C | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle calibrated with air and water. |
| Refractive Index at 20 C | Refractometry | Measures bending of light through sample at specified temperature to infer purity and composition. |
| Residue on Evaporation | Gravimetric Analysis | Quantifies non-volatile impurities by evaporating known sample mass and weighing residual solids after drying. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Detects trace metal contaminants by measuring absorption of characteristic wavelength light by ground-state atoms in flame or graphite furnace. |
| Chloride Content | Potentiometric Titration with AgNO3 | Determines chloride ions by titration with silver nitrate using silver electrode for endpoint detection. |
| Aldehyde Impurities | UV-Vis Spectrophotometry after derivatization with DNPH | Measures aldehydes via absorbance of hydrazone derivatives formed with 2,4-dinitrophenylhydrazine at ~450 nm. |
| Residual Solvents (e.g., Ethyl Acetate, Methanol) | Headspace Gas Chromatography (HS-GC) | Quantifies volatile organic solvents by analyzing equilibrium vapor phase above sample in sealed vial. |
| Optical Rotation | Polarimetry | Measures specific rotation of chiral compound using plane-polarized light to confirm stereochemical integrity. |
