Manufacturing Quality Control of 3-NITROPHENYLACETYLENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at ~254 nm, comparing peak area to calibrated standard. |
| Related Substances | HPLC-DAD or HPLC-MS | Separates and detects impurities (e.g., 3-nitrobenzaldehyde, 1-ethynyl-3-aminobenzene) via retention time and spectral/mass matching. |
| Residual Solvents | GC-FID | Quantifies volatile solvents (e.g., acetone, THF, toluene) using gas chromatography with flame ionization detection against internal standard. |
| Water Content | Karl Fischer Titration (Coulometric) | Determines trace water by electrochemical iodine generation and stoichiometric reaction with water in anhydrous methanol-based medium. |
| Heavy Metals (as Pb) | ICP-MS | Measures trace metal contaminants (Pb, Cd, Hg, As) after acid digestion using inductively coupled plasma mass spectrometry for sub-pptr sensitivity. |
| Acidity (as HCl) | Acid-Base Titration (Non-aqueous) | Titrates acidic impurities (e.g., residual HCl from synthesis) with tetrabutylammonium hydroxide in anhydrous acetonitrile using potentiometric endpoint detection. |
| Melting Point | Capillary Melting Point Apparatus | Determines purity-dependent solid–liquid transition temperature range using calibrated capillary apparatus per USP <741>. |
| Appearance & Color | Visual Inspection / APHA Color Scale | Assesses physical state (crystalline solid), color (pale yellow to amber), and clarity against APHA scale under controlled lighting. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content after high-temperature (700–800 °C) ignition of sample in platinum crucible, per USP <281>. |
