Manufacturing Quality Control of 4-BROMO-2,2-DIPHENYLBUTYRONITRILE
| Test Item | Common Test Methods | Method Overview |
|---|---|---|
| Assay (Purity) | High-Performance Liquid Chromatography (HPLC) | Using a reversed-phase C18 column and a UV detector (e.g., 254 nm), the purity is evaluated by determining the peak area percentage of the main component using external standard method or area normalization method. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Under the same HPLC conditions, impurity peaks are separated and quantified to identify known or unknown impurities and control the total impurity limit. |
| Structure Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Confirm the molecular structure by analyzing hydrogen and carbon signals using 1H NMR and 13C NMR. |
| Fourier Transform Infrared Spectroscopy (FT-IR) | Detect characteristic functional group absorption peaks (e.g., C≡N, C–Br, aromatic ring C–H), to assist in structural confirmation. | |
| Mass Spectrometry (MS) | Determine the molecular weight by measuring the molecular ion peak ([M]⁺ or [M+H]⁺) using electrospray ionization (ESI) or electron impact ionization (EI). | |
| Water Content | Karl Fischer Titration | Quantitatively determine the water content based on the reaction between iodine and sulfur dioxide in a pyridine/methanol system through titration. |
| Residual Solvents | Gas Chromatography (GC) | Analyze common organic solvents (e.g., toluene, dichloromethane) using headspace or direct injection, with polar or non-polar capillary columns and an FID detector. |
| Melting Point | Melting Point Apparatus | Determine the melting temperature range of the sample using the capillary method or an automatic melting point apparatus, as a physical constant for preliminary identification and purity assessment. |
| Appearance and Color | Visual Colorimetry | Observe the appearance (e.g., white to off-white crystalline powder) and compare the color intensity with standard color solutions under specified conditions. |
| pH Value (if soluble in water) | pH Meter Method | Prepare a solution (or suspension) of the sample at a certain concentration, and measure its pH using a calibrated pH meter. |
