Manufacturing Quality Control of Ethyl 3-bromopropionate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 3-bromopropionic acid ethyl ester peak area against a calibration curve using an internal or external standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration based on the stoichiometric reaction of iodine with water in pyridine/methanol medium. |
| Acid Value | Acid-Base Titration (NaOH standard solution) | Determines free acid content by neutralizing acidic impurities with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled high-temperature ashing and weighing. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantifies metals (e.g., Pb, Cd, Hg, As) by measuring absorption of characteristic atomic spectral lines after acid digestion. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Bromide Impurity | Potentiometric Titration with AgNO3 | Measures bromide ion concentration via argentometric titration using silver nitrate and a silver electrode. |
| Color | Visual Comparison Against Hazen (APHA) Scale | Evaluates yellowness intensity by comparing sample color to standardized platinum-cobalt solutions under controlled lighting. |
| Density | Digital Density Meter (Oscillating U-tube) | Determines density from the resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index | Refractometry (Abbe Refractometer) | Measures refractive index based on critical angle of total internal reflection at the prism-sample interface. |
| Boiling Range | Distillation (Micro or Semi-micro Apparatus) | Determines temperature interval over which 90% of the sample distills under specified atmospheric pressure and heating rate. |
| Organic Volatile Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and quantifies residual solvents or low-boiling impurities by retention time and mass spectral fragmentation patterns. |
