Manufacturing Quality Control of 2-broMo-4,4'-di-tert-butylbiphenyl
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time relative to reference standards or spiked samples. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common organic solvents (e.g., toluene, heptane) based on calibrated response factors. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generated electrochemically to react stoichiometrically with water in the sample. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, using mass spectrometry for high sensitivity and selectivity. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions after sample dissolution and filtration; quantified via external calibration. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after controlled ashing at 600 C, expressed as weight percent. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature range using calibrated capillary apparatus under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of solid material against standard white background under controlled lighting. |
| Bulk Density | Graduated Cylinder Method | Mass per unit volume measured by gently pouring dried sample into a calibrated cylinder and tapping to settle. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as function of angle to derive particle size distribution in dispersed dry powder. |
| Organic Volatile Impurities (OVI) | GC-MS | Targeted and untargeted screening of volatile organics using gas chromatography coupled with mass spectrometry for identification and quantification. |
