Manufacturing Quality Control of TERT-BUTYL ETHYL MALONATE
| 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 calibrated column and carrier gas. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of acidic impurities by standardized sodium hydroxide solution, detected potentiometrically or with phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after controlled high-temperature ashing of the sample. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal content via absorption of characteristic wavelength light by ground-state atoms in a flame or graphite furnace. |
| Chloride Content | Ion Chromatography (IC) | Separation and quantification of chloride anions using an ion-exchange column and conductivity detection. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Evaluation of sample color intensity against platinum-cobalt standard solutions measured at 455 nm. |
| Density at 20 degC | Digital Density Meter | Determination of mass per unit volume using oscillating U-tube principle with temperature-controlled measurement. |
| Refractive Index at 20 degC | Refractometry | Measurement of light bending angle as it passes through the sample, correlated to molecular concentration and purity. |
| Residual Solvents (e.g., THF, EtOAc) | Headspace Gas Chromatography (HS-GC) | Volatile organic solvents are vaporized in sealed vials and quantified by GC-FID after partitioning into headspace. |
| Appearance | Visual Inspection | Assessment of physical state, clarity, and presence of particulates or phase separation under controlled lighting conditions. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light caused by chiral molecules in solution at specified concentration and path length. |
