Manufacturing Quality Control of 2-Bromo-4'-nitroacetophenone
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities based on retention time and relative response factors using gradient elution and UV detection. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents by gas chromatography with flame ionization detection using headspace sampling. |
| Moisture Content | Karl Fischer Titration | Volumetric titration based on the stoichiometric reaction of water with iodine, sulfur dioxide, and pyridine in methanol medium. |
| Heavy Metals | ICP-OES | Multi-element quantification after acid digestion by measuring atomic emission intensities at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride anions using suppressed conductivity detection after anion-exchange chromatography. |
| Sulfated Ash | Gravimetric Analysis | Determination of inorganic residue mass after controlled high-temperature incineration followed by cooling and weighing. |
| Melting Point | Capillary Melting Point Apparatus | Measurement of temperature range over which solid transitions to liquid, determined by optical observation of meniscus movement in capillary tube. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against defined standards under controlled lighting and viewing conditions. |
| Organic Volatile Impurities (OVI) | GC-FID | Specific quantification of residual process-related volatiles (e.g., acetone, ethyl acetate) using calibrated GC-FID with appropriate column and temperature program. |
| Acid Value | Acid-Base Titration | Neutralization of acidic impurities with standardized sodium hydroxide solution using phenolphthalein indicator or potentiometric endpoint detection. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered light intensity patterns from dispersed particles to calculate size distribution based on Mie scattering theory. |
