Manufacturing Quality Control of Benzene, 1,3-dibromo-2,5-dichloro-
| Detection Item | Common Detection Method | Method Overview |
|---|---|---|
| Purity Analysis | Gas Chromatography (GC) | Utilizes gas chromatography to separate components in the sample, followed by flame ionization detection (FID) or mass spectrometry (MS) for quantification. This method accurately determines the purity of 2,5-dichloro-1,3-dibromobenzene and serves as a core technique for routine quality control. |
| Organic Impurity Detection | Gas Chromatography-Mass Spectrometry (GC-MS) | Combines the separation capability of gas chromatography with the identification power of mass spectrometry, enabling effective detection and quantification of trace impurities (e.g., isomers, by-products), especially suitable for complex matrices. |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Suitable for thermally unstable or low-volatility compounds. Uses a reversed-phase C18 column with UV detection at wavelengths of 200–250 nm, enabling high-precision content determination. |
| Structural Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | ¹H NMR and ¹³C NMR provide detailed molecular structural information, used to confirm the chemical structure of 2,5-dichloro-1,3-dibromobenzene and rule out isomers or structural defects. |
| Molecular Weight Identification | Liquid Chromatography-Mass Spectrometry (LC-MS) | Applicable to non-volatile or thermally unstable samples. Achieves accurate molecular weight determination via electrospray ionization (ESI) or atmospheric pressure chemical ionization (APCI), supporting structural confirmation. |
| Residual Solvent Testing | Gas Chromatography (GC-FID/MS) | Used to detect residual organic solvents (e.g., toluene, ethanol, acetone) from synthesis processes, meeting ICH Q3A/B requirements to ensure product safety and regulatory compliance. |
| Chlorine/Bromine Elemental Content Analysis | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Provides precise measurement of total chlorine and bromine content in the sample, verifying whether it matches theoretical values, thereby assisting in assessing raw material purity and reaction completeness. |
