Manufacturing Quality Control of TERT-BUTYL 5-BROMOISOINDOLINE-2-CARBOXYLATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at characteristic wavelength based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities by retention time and peak area relative to main peak using gradient elution. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, DCM, MeOH) by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration where iodine reacts stoichiometrically with water in anhydrous methanol-based medium. |
| Heavy Metals | ICP-OES | Quantifies elemental impurities (e.g., Pb, Cd, Ni, Fe) after acid digestion by measuring atomic emission intensities at element-specific wavelengths. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after anion exchange separation. |
| Residual Palladium | ICP-MS | Detects trace Pd catalyst residues following microwave-assisted digestion by measuring isotopic mass signals with high sensitivity and selectivity. |
| Acid Value | Acid-Base Titration | Determines free HCl content by titration with standardized NaOH solution using potentiometric or indicator endpoint detection. |
| Particle Size Distribution | Laser Diffraction | Measures dry or wet dispersed particle size distribution by analyzing angular dependence of laser light scattering intensity. |
| Bulk Density | USP <616> Tap Density Method | Determines mass per unit volume after controlled mechanical tapping of a powder sample in a calibrated cylinder. |
| Microbial Limits | Membrane Filtration | Detects aerobic microorganisms by filtration, membrane transfer to solid growth media, and colony enumeration after incubation. |
| Optical Rotation | Polarimetry | Measures specific rotation using sodium D-line light passing through a solution to assess chiral purity and enantiomeric identity. |
