Manufacturing Quality Control of Methyl 4-bromocrotonate
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, physical state, and clarity under natural or standard lighting to determine the presence of impurities or foreign matter. |
| Assay | Gas Chromatography (GC) | Quantitative analysis of the active ingredient using capillary column gas chromatography by comparing retention time and peak area with reference standards. |
| Purity Analysis | High-Performance Liquid Chromatography (HPLC) | Utilize a reversed-phase C18 column and UV detector (e.g., 210 nm) to evaluate the purity of the main peak and assess the number and size of impurity peaks. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Determine organic solvents potentially remaining from manufacturing (e.g., methanol, dichloromethane), in compliance with ICH Q3C guidelines. |
| Moisture Content | Karl Fischer Titration | Precisely measure water content in the sample via titration; suitable for quality control of moisture-sensitive organic intermediates. |
| Structural Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Analyze proton (¹H-NMR) and carbon (¹³C-NMR) spectra to confirm molecular structure and stereochemical characteristics. |
| Structural Confirmation | Mass Spectrometry (MS) | Determine molecular ion peaks using EI-MS or ESI-MS to verify molecular weight and assist in structural identification. |
| Melting Point / Boiling Point | Melting Point Apparatus or Differential Scanning Calorimetry (DSC) | Measure the melting temperature range or phase transition behavior for substance identification and preliminary purity assessment. |
| Heavy Metal Residues | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Detect residual heavy metal elements such as lead, arsenic, and mercury to ensure compliance with pharmaceutical or export standards (e.g., ICH Q3D). |
| Chloride/Bromide Identification | Ion Chromatography (IC) or Chemical Colorimetric Method | Qualitative or quantitative detection of bromide ions to verify the presence of bromine in the final product. |
