Manufacturing Quality Control of 2-N-PROPYLPROPANE-1,3-DIOL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area against calibrated standard; uses internal or external standardization. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein or potentiometric endpoint. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Compares sample color to platinum-cobalt standards; quantifies yellowness index in APHA units. |
| Specific Gravity | Digital Density Meter or Pycnometer | Determines mass per unit volume relative to water at specified temperature (e.g., 20/20 degC). |
| Refractive Index | Refractometry at 20 degC | Measures bending of light through sample to infer purity and composition based on known refractive index range. |
| Residue on Evaporation | Gravimetric Analysis | Evaporates known volume under controlled conditions and weighs non-volatile residue after drying. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomizing sample and measuring absorption of characteristic wavelength radiation. |
| Chloride Content | Potentiometric Titration with AgNO3 | Titration with silver nitrate using silver indicator electrode; detects endpoint via potential change from AgCl precipitation. |
| Aldehyde Impurities | Spectrophotometry after Reaction with DNPH | Derivatizes aldehydes to hydrazones, then measures absorbance at ~450 nm for quantification. |
| Non-Volatile Residue | Gravimetric Analysis | Heats sample to constant weight at 105 degC and determines residual solids by mass difference. |
| Optical Rotation | Polarimetry | Measures rotation of plane-polarized light caused by chiral centers; confirms stereochemical consistency. |
