Manufacturing Quality Control of 1-ETHYNYL-3 5-DIFLUOROBENZENE 97
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Related Substances | Gas Chromatography (GC) with FID or MS detection | Separation and identification of impurities by retention time and/or mass spectral matching; quantification relative to main peak. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile solvents are equilibrated in headspace vial, injected into GC column, and quantified using external calibration standards. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine is generated in situ to react stoichiometrically with water; endpoint detected amperometrically. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Sample digested in acid matrix; elemental emission intensities measured at characteristic wavelengths and compared to calibration curve. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Anionic impurities separated on anion-exchange column and quantified via suppressed conductivity detection. |
| Acid Value | Acid-Base Titration (NaOH standard solution) | Neutralization of acidic impurities with standardized sodium hydroxide solution using phenolphthalein indicator or potentiometric endpoint. |
| Appearance | Visual Inspection (against white/black background) | Assessment of physical state, color, and clarity in a transparent container under controlled lighting conditions. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as the temperature range over which solid transforms to liquid, determined by controlled heating rate. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash method) | Sample ignited at 700-800 C after sulfuric acid treatment; residual inorganic matter weighed following cooling in desiccator. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution, indicating chiral purity if applicable (though compound is achiral, used for consistency check). |
| Bulk Density | Tap Density Measurement (ASTM D1895) | Mass per unit volume determined after mechanically tapping a graduated cylinder containing a known mass of sample until volume stabilizes. |
