Manufacturing Quality Control of 1121057-75-7
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 210-230 nm; peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., boronic acid precursors, dehydrogenated analogs) via gradient HPLC with UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, toluene, methanol) using capillary GC with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration with iodine-based reagent; based on stoichiometric reaction with water. |
| Chloride Content | Potentiometric Titration | Quantifies chloride ions using silver nitrate titrant and silver/silver chloride electrode; endpoint detected by potential change. |
| Heavy Metals | ICP-OES | Simultaneously detects Pb, Cd, Hg, As, Ni, and other regulated metals after acid digestion and plasma excitation. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content by high-temperature incineration (500-600 C) followed by precise weighing of residue. |
| Optical Rotation | Polarimetry | Determines specific rotation using sodium D-line light; confirms chiral integrity and absence of racemization. |
| pH (1% w/v aqueous solution) | pH Meter | Measures hydrogen ion activity in aqueous suspension using calibrated glass electrode; reflects hydrochloride salt stability. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry powder size distribution via Mie scattering theory using dispersed aerosol or liquid suspension. |
| Microbial Limits | Membrane Filtration | Detects aerobic microorganisms and specified pathogens (e.g., E. coli, S. aureus) by filtration, culture, and colony enumeration. |
| X-Ray Powder Diffraction Pattern | XRPD | Confirms crystalline phase identity and polymorphic form by comparing diffraction angles and intensities to reference pattern. |
