Manufacturing Quality Control of 1,1-Bis(hydroxymethyl)cyclopropane
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component using retention time and peak area against calibrated standard. |
| Water Content | Karl Fischer Titration | Measures water via electrochemical reaction between iodine, sulfur dioxide, and water in methanol-based solvent. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralizes acidic impurities; endpoint detected potentiometrically or with phenolphthalein indicator. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Compares sample color to platinum-cobalt standard solutions using visual matching or absorbance at 455 nm. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by measuring absorbance of ground-state atoms in flame or graphite furnace. |
| Chloride Content | Ion Chromatography (IC) or Potentiometric Titration | Separates and quantifies chloride ions via conductivity detection (IC) or silver nitrate titration with Ag electrode. |
| Specific Optical Rotation | Polarimetry | Measures angle of rotation of plane-polarized light caused by chiral molecules in solution. |
| Refractive Index | Refractometry | Determines refractive index at specified temperature using Abbe refractometer based on critical angle principle. |
| Density | Oscillating U-tube Densitometry | Measures density from resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Residual Solvents (e.g., Methanol, THF) | Headspace Gas Chromatography (HS-GC) | Quantifies volatile solvents by analyzing equilibrium vapor phase above sample in sealed vial. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) with UV detection | Separates and quantifies structurally related impurities using reversed-phase column and UV absorbance at 210 nm. |
