Manufacturing Quality Control of DIETHYL SEC-BUTYLMALONATE
| 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 stoichiometric reaction between water, iodine, sulfur dioxide, and base 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 455 nm | Evaluates yellowness by matching sample color to APHA platinum-cobalt standard scale. |
| Density at 20 degC | Digital Density Meter (Oscillating U-tube) | Determines density from resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index at 20 degC | Abbe Refractometer | Measures bending of light passing through sample to determine refractive index at specified temperature. |
| Residue on Evaporation | Gravimetric Analysis | Weighs non-volatile residue remaining after controlled evaporation of a known sample mass under specified conditions. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after wet digestion by measuring absorption of characteristic atomic spectral lines. |
| Chloride Content | Potentiometric Titration with AgNO3 | Detects chloride ions via silver nitrate titration using silver indicator electrode and reference electrode. |
| Ethanol Content | Gas Chromatography (GC) with FID | Separates and quantifies residual ethanol using internal standard and calibrated GC method. |
| Aldehyde Impurities | UV-Vis Spectrophotometry after Derivatization with DNPH | Measures aldehyde-DNPH hydrazone adduct absorbance at ~360 nm for quantification. |
| Non-Volatile Matter | Gravimetric Analysis | Determines insoluble particulates by filtration, drying, and weighing of retained residue on pre-weighed membrane filter. |
