Manufacturing Quality Control of 1,3-Benzenedimethanol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 1,3-benzenedimethanol by retention time and peak area comparison against a certified reference standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration based on the stoichiometric reaction of iodine with water in pyridine/methanol medium. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Determines acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometry at 455 nm | Evaluates yellowness by matching sample color to APHA platinum-cobalt standards or measuring absorbance at 455 nm. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing of the cooled crucible. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomization and absorption measurement at characteristic wavelengths after acid digestion. |
| Chloride Content | Ion Chromatography (IC) or Potentiometric Titration | Separates and quantifies chloride ions using anion-exchange column or detects endpoint via silver nitrate titration with chloride-selective electrode. |
| Aldehyde Impurities (e.g., Benzaldehyde) | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and quantifies volatile aldehyde impurities by retention time and mass spectral fragmentation patterns. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) with UV detection | Separates and quantifies structurally related organic impurities using reversed-phase C18 column and UV absorbance at 210–280 nm. |
| Density at 20 degC | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle calibrated with air and water standards. |
| Refractive Index at 20 degC | Abbe Refractometer | Measures bending of light at air-sample interface to determine refractive index as a function of molecular polarizability and concentration. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity based on crystalline lattice disruption. |
