Manufacturing Quality Control of 2,4-Dichlorobutyrophenone
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 254 nm, based on peak area comparison against reference standard. |
| Related Substances | HPLC-DAD | Detects and quantifies impurities using HPLC with diode array detection, comparing retention times and spectra to known impurity standards. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., acetone, methanol) by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine generation in pyridine-free reagent system. |
| Heavy Metals | ICP-OES | Quantifies Pb, Cd, Hg, As, and other metals after acid digestion by measuring atomic emission intensities at characteristic wavelengths. |
| Chloride Content | Potentiometric Titration | Measures inorganic chloride ions using silver nitrate titrant and silver/silver chloride indicator electrode. |
| Acid Value | Acid-Base Titration | Determines free acidic impurities by titration with standardized potassium hydroxide solution using phenolphthalein indicator. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid using calibrated capillary tube method per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particles or discoloration against white/black background under controlled lighting. |
| Loss on Drying | Gravimetric Method | Determines volatile matter by measuring mass loss after drying at specified temperature (e.g., 105 C) for fixed duration. |
| Residue on Ignition | Sulfated Ash Test | Measures non-volatile inorganic residue after high-temperature ignition (700–800 C) following sulfuric acid treatment. |
| Specific Optical Rotation | Polarimetry | Measures chiral purity (if applicable) by determining rotation angle of plane-polarized light in solution at specified concentration and wavelength. |
