Manufacturing Quality Control of 4-Chlorobutanal diethyl acetal
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color and state of the sample under natural light or standard light sources to determine if it is a colorless to pale yellow transparent liquid, and check for any suspended particles or sediment. |
| Content Determination | Gas Chromatography (GC) | Use capillary column gas chromatography with a hydrogen flame ionization detector (FID), and determine the content of the main component using external standard or internal standard methods, which offer high separation efficiency and sensitivity. |
| Impurity Analysis | Gas Chromatography-Mass Spectrometry (GC-MS) | Combine the separation capability of GC with the qualitative power of MS to identify and quantify potential organic impurities, such as unreacted raw materials, by-products, or degradation products. |
| Water Content | Karl Fischer Titration | Determine the trace amount of water in the sample using electrochemical titration principles, suitable for quality control of moisture-sensitive organic compounds. |
| Acid Value (Acidity) | Acid-Base Titration | Determine the free acid in the sample using a standard sodium hydroxide solution, calculate the acid value expressed as mg KOH/g, and assess the hydrolysis degree during storage. |
| Density | Densitometer Method or Specific Gravity Bottle Method | Determine the density of the sample at a specified temperature (e.g., 20°C) to verify purity and consistency. |
| Refractive Index | Refractometry | Measure the refractive index of the sample using an Abbe refractometer at a standard temperature (e.g., 20°C), serving as a physical constant for identification and purity assessment. |
| Boiling Point / Boiling Range | Distillation Method | Determine the initial boiling point and dry point of the sample to establish the boiling range, assessing volatility and component uniformity. |
| Residual Solvents | Gas Chromatography (GC) | According to pharmacopoeia or relevant standards (e.g., ICH Q3C), detect residual organic solvents such as ethanol and dichloromethane used in production. |
| Infrared Spectroscopy (IR) Identification | Fourier Transform Infrared Spectroscopy (FTIR) | Obtain the infrared absorption spectrum of the sample and compare it with standard spectra to confirm characteristic functional groups (e.g., C–Cl, C–O–C) in the molecular structure. |
