Manufacturing Quality Control of 2,7-Di-tert-butylpyrene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at characteristic wavelength (e.g., 254 nm) and external standard calibration. |
| Related Substances | HPLC-DAD | Identifies and quantifies structurally related impurities (e.g., mono-tert-butyl isomers, unreacted pyrene) via retention time and spectral matching. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., toluene, THF) using capillary GC with flame ionization detection and internal standard calibration. |
| Moisture Content | Karl Fischer Titration | Determines water content by coulometric or volumetric titration based on iodine consumption in a pyridine-free reagent system. |
| Heavy Metals | ICP-MS | Measures trace metal contaminants (e.g., Pd, Ni, Fe) after acid digestion using inductively coupled plasma mass spectrometry with isotopic detection. |
| Chloride Content | Ion Chromatography | Quantifies chloride ions released from potential alkyl chloride impurities or catalyst residues using suppressed conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated digital apparatus per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles against reference standards under controlled lighting conditions. |
| Bulk Density | ASTM D1895 Method A | Measures mass per unit volume of freely settled powder using a standardized graduated cylinder and balance. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of dry powder using Mie scattering theory and calibrated optical model. |
| Sulfated Ash | Gravimetric Analysis | Determines inorganic residue after combustion with sulfuric acid treatment and high-temperature ashing (600-800 C). |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light in solution to confirm chiral purity and absence of optically active contaminants. |
