Manufacturing Quality Control of 2,5-Di-tert-butylhydroquinone
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Using a reverse-phase C18 chromatographic column, with methanol-water or acetonitrile-water as the mobile phase, and a UV detector (UV, approximately 280 nm) for detection. Quantification is performed using the external standard method, offering high sensitivity and good separation performance. |
| Purity Analysis | Gas Chromatography-Mass Spectrometry (GC-MS) | After appropriate derivatization of the sample, it is injected into the system. Separation is achieved by gas chromatography, and qualitative and semi-quantitative analysis is conducted via mass spectrometry. This method is suitable for derivatives with good volatility. |
| Structural Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Using ¹H-NMR and ¹³C-NMR to confirm the molecular structure of the compound. Structural information and substituent positions are determined based on characteristic peak positions and integration areas. |
| Residual Solvent Detection | Gas Chromatography (GC) | According to pharmacopoeias or relevant standards (e.g., ICH Q3C), residual organic solvents (such as methanol, ethanol, acetone, etc.) from the production process are detected using headspace injection-GC-FID. |
| Moisture Content | Karl Fischer Titration | Determines the moisture content in the sample using electrochemical titration principles. It includes volumetric and coulometric methods, suitable for trace moisture detection with high accuracy. |
| Melting Point | Capillary Melting Point Method | The sample is placed in a capillary tube and gradually heated in a melting point apparatus. The initial and final melting temperatures are observed, which are used to preliminarily assess the purity and consistency of the substance. |
| Related Substances (Impurities) Test | High-Performance Liquid Chromatography (HPLC) | Using gradient or isocratic elution, impurities appearing before and after the main component are detected. Impurity contents are calculated to evaluate the purity and stability of the sample. |
| UV Absorption Characteristics | UV-Visible Spectrophotometry (UV-Vis) | Scanning in the wavelength range of 200–400 nm to determine the maximum absorption wavelength (λmax) and absorbance. Used for qualitative identification and auxiliary quantification. |
