Manufacturing Quality Control of (S)-(+)-1,3-BUTANEDIOL
| 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 chiral or non-chiral column. |
| Optical Rotation | [alpha]D Measurement using Polarimetry | Measures the angle of rotation of plane-polarized light caused by the chiral compound in solution at specified concentration, temperature, and wavelength. |
| Water Content | Karl Fischer Titration (Coulometric or Volumetric) | Electrochemical titration where iodine reacts stoichiometrically with water; endpoint detected amperometrically or potentiometrically. |
| Residue on Ignition | Gravimetric Analysis after High-Temperature Ashing | Sample is ignited at 700-800 C to volatilize organic matter; inorganic residue is weighed as percent of original sample. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after acid digestion | Digestion converts metals to soluble ionic forms; AAS quantifies metal concentration via absorption of element-specific hollow cathode lamp radiation. |
| Chloride Impurity | Ion Chromatography (IC) with Conductivity Detection | Separation of anions on ion-exchange column followed by quantitative detection based on electrical conductivity of eluted chloride ions. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH and phenolphthalein indicator | Neutralization of acidic impurities with standardized sodium hydroxide solution; endpoint detected by color change of indicator. |
| Specific Gravity | Digital Density Meter (Oscillating U-tube principle) | Measures density via resonant frequency shift of a vibrating U-shaped tube filled with sample at controlled temperature. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Compares sample color to platinum-cobalt standard scale; or measures absorbance at 455 nm in 10-mm cell against water blank. |
| Residual Solvents (e.g., Ethanol, Acetone) | Headspace Gas Chromatography (HS-GC) with FID | Volatiles are equilibrated in headspace above sample, injected into GC, and quantified by peak area relative to calibration standards. |
| Non-Volatile Residue | Evaporation and Gravimetric Weighing | Sample is evaporated to dryness under controlled conditions; residue is weighed and expressed as mass percent. |
| Stereochemical Purity (Enantiomeric Excess) | Chiral Gas Chromatography (cGC) or Chiral HPLC | Separation of enantiomers on chiral stationary phase; ee calculated from relative peak areas of (S)- and (R)-enantiomer peaks. |
