Manufacturing Quality Control of 2-Phenyl-1,3-propanediol
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, condition, and presence of impurities under natural light or standard light source. It should be a clear to slightly yellow transparent liquid. |
| Identification | Infrared Spectroscopy (IR) | Determine the infrared absorption spectrum using an infrared spectrometer and compare it with a standard spectrum to confirm characteristic functional groups (e.g., hydroxyl, benzene ring). |
| Proton Nuclear Magnetic Resonance (¹H NMR) | Determine the chemical shift of hydrogen atoms using a nuclear magnetic resonance spectrometer to verify whether the proton signals match those of 2-phenyl-1,3-propanediol. | |
| Content Determination | Gas Chromatography (GC) | Use capillary column gas chromatography with area normalization or internal standard method to determine the main component content. Suitable for samples that are volatile and thermally stable. |
| High-Performance Liquid Chromatography (HPLC) | Use a reverse-phase C18 chromatography column with a UV detector (e.g., 210–220 nm) and external standard method for quantification. Suitable for thermally unstable or highly polar samples. | |
| Moisture | Karl Fischer Titration | Determine the trace moisture content using volumetric or coulometric Karl Fischer titration. |
| pH Value | pH Meter Method | Determine the acidity or alkalinity by preparing a certain concentration aqueous solution (e.g., 10%) and measuring it with a calibrated pH meter. |
| Residue on Ignition | Gravimetric Method | Weigh the inorganic residue after heating the sample at high temperature (typically 700–800°C) to evaluate the total amount of inorganic impurities. |
| Heavy Metals | Atomic Absorption Spectrometry (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) |
Determine the content of heavy metals such as lead, arsenic, cadmium, and mercury using AAS or ICP-MS after digesting the sample, ensuring compliance with pharmacopoeia or industry limit requirements. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Use gradient or isocratic elution HPLC methods to separate and detect possible synthetic by-products or degradation impurities, usually reported as a percentage of the main peak area. |
