Manufacturing Quality Control of 57671-28-0
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a polar capillary column. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in anhydrous methanol/pyridine medium. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometry at 455 nm | Measurement of yellowness intensity by comparing sample absorbance at 455 nm to APHA color scale standards. |
| Residue on Ignition | Gravimetric Analysis | Weighing of non-volatile residue remaining after high-temperature ashing of a weighed sample. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after acid digestion, based on absorption of characteristic atomic spectral lines. |
| Chloride Content | Potentiometric Titration with AgNO3 | Titration with silver nitrate using a silver electrode to detect endpoint via potential change from AgCl precipitation. |
| Refractive Index | Refractometry at 20 C | Measurement of light bending angle through the liquid sample relative to air, correlated to purity and concentration. |
| Density at 20 C | Oscillating U-tube Densitometry | Determination of mass per unit volume via precise measurement of oscillation period of a filled U-shaped glass tube. |
| Flash Point | Closed Cup Pensky-Martens Tester | Measurement of lowest temperature at which vapors above the sample ignite momentarily under controlled conditions. |
| Non-Volatile Residue | Gravimetric Evaporation | Weighing of residue left after evaporating a fixed volume of sample under controlled heating and vacuum. |
| Benzyl Alcohol Impurity | Gas Chromatography (GC) with FID detection | Separation and quantification of residual benzyl alcohol using retention time matching and external calibration. |
