Manufacturing Quality Control of 5-Bromo-2-methylpyridine
| Detection Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance and Physical Properties | Visual Inspection + Physical Property Measurement | Observe sample color and state (typically colorless to pale yellow liquid or low-melting solid); determine melting point or boiling point range, conforming to pharmacopoeia or company specifications. |
| Purity (Main Component Content) | High-Performance Liquid Chromatography (HPLC) | Use C18 column with methanol-water or acetonitrile-water as mobile phase, UV detector (254 nm), external standard or internal standard method for quantification; typically requires ≥98.0%. |
| Impurity Profile Analysis | HPLC (Impurity Detection) | Same HPLC method, reduce detection wavelength or use gradient elution to separate and quantify known impurities (e.g., unreacted starting materials, debromination products, oxidation by-products), controlled per ICH Q3B guidelines for individual and total impurity limits. |
| Residual Solvents | Gas Chromatography (GC) | Use headspace or direct injection, DB-624 or HP-INNOWAX column, FID detector; detect residual solvents such as methanol, ethanol, acetone, dichloromethane according to ICH Q3C guidelines. |
| Moisture Content | Karl Fischer Titration | Use coulometric or volumetric Karl Fischer reagent to accurately measure trace water content; control moisture at ≤0.5% (adjustable based on application) to prevent hydrolysis or instability. |
| Bromine Content | Combustion Ion Chromatography / X-ray Fluorescence (XRF) | Determine bromide ions in combustion-derived solution via ion chromatography, or non-destructively measure bromine content using XRF; verify bromine atom ratio matches theoretical value (theoretical Br ≈ 50.2%). |
| Melting Point / Boiling Point | Melting Point Apparatus / Boiling Point Determination Device | Determine melting point (literature value ~35–40°C) or atmospheric boiling point (~210–215°C), serving as physical constants for identification and purity assessment. |
| UV-Visible Absorption Spectroscopy | UV-Vis Spectrophotometry | Dissolve sample in ethanol or methanol, measure absorption spectrum from 200–400 nm; characteristic absorption peak around 260–270 nm used for preliminary identification and concentration estimation. |
| Nuclear Magnetic Resonance (¹H NMR) | Proton Nuclear Magnetic Resonance | Use CDCl₃ as solvent; confirm molecular structure and identify impurities via chemical shifts (e.g., 2-CH₃: δ ≈ 2.5 ppm; Ar-H: δ ≈ 7.2–8.0 ppm) and integration ratios. |
| Gas Chromatography-Mass Spectrometry (GC-MS) | GC-MS | Used for qualitative analysis of unknown impurities; match mass spectral fragments against databases (e.g., NIST) to identify potential degradation products or synthetic by-products. |
