Manufacturing Quality Control of 2-N-PENTYLPROPANE-1,3-DIOL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area against calibrated standard. |
| Water Content | Karl Fischer Titration | Measures water via electrochemical reaction between iodine, sulfur dioxide, and water in methanol medium. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Compares sample color to APHA platinum-cobalt standard scale using visual or absorbance-based assessment. |
| Density at 20 C | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle with temperature control. |
| Refractive Index at 20 C | Refractometry | Measures bending of light through liquid sample to determine purity and concentration. |
| Residue on Evaporation | Gravimetric Analysis | Evaporates known volume to dryness and weighs non-volatile residue after controlled heating. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies trace metal content by measuring absorption of characteristic wavelength light by ground-state atoms in flame. |
| Chloride Content | Ion Chromatography (IC) or Potentiometric Titration with AgNO3 | Separates and quantifies chloride ions via conductivity detection or silver nitrate titration with endpoint detection. |
| Aldehyde Impurities | Spectrophotometric DNPH Derivatization | Derivatizes aldehydes with 2,4-dinitrophenylhydrazine and measures absorbance of resulting hydrazone. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Extracts and separates volatile solvents from sample matrix using heated headspace and GC-FID analysis. |
| Optical Rotation | [a]D at 20 C | Measures rotation of plane-polarized light by chiral molecules in solution using polarimeter. |
