Manufacturing Quality Control of (-)-DIBUTYL-D-TARTRATE
| 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 non-polar capillary column. |
| Specific Optical Rotation | [alpha]D at 20 C | Measurement of the angle of rotation of plane-polarized light using a digital polarimeter, reported as degrees per dm·g/mL. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of free carboxylic acid groups using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemical generation of iodine to react stoichiometrically with water; quantitation based on charge consumption. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Heating sample at 700-800 C to oxidize organic matter, followed by weighing of inorganic residue. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after wet digestion, using lead as the reference element and air-acetylene flame. |
| Chloride Impurity | Ion Chromatography (IC) with Conductivity Detection | Separation of chloride anions on an anion-exchange column and detection via suppressed conductivity. |
| Residual Solvents (e.g., n-Butanol) | Gas Chromatography (GC) with Headspace Sampling | Headspace equilibration followed by GC-FID analysis using a polar column and internal standard calibration. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Comparison of sample solution color intensity against platinum-cobalt standards or absorbance measurement at specified wavelength. |
| Density at 20 C | Oscillating U-tube Densitometry | Measurement of sample density based on resonant frequency shift of a vibrating U-shaped glass tube filled with sample. |
| Refractive Index at 20 C | Digital Refractometry | Determination of refractive index by measuring critical angle of total internal reflection at the prism-sample interface. |
| Non-Volatile Residue | Gravimetric Evaporation | Evaporation of a known volume under controlled temperature and pressure, followed by weighing of residual solids. |
