Industrial Applications of 144226-16-4
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Organic synthesis intermediate | Used in the synthesis of biologically active drug molecules as an amine-protecting intermediate in multistep syntheses |
| Fine chemicals | Introduction of protecting groups | Employs BOC (tert-butoxycarbonyl) to protect amino groups during peptide or complex molecule synthesis, enhancing reaction selectivity |
| Chemical research | Nitro compound transformation | Reduces nitro groups to amino groups, yielding derivatives such as N-BOC-4-amino-phenethylamine for subsequent functionalization |
Manufacturing Quality Control of 144226-16-4
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase chromatography with UV detection at 254 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., deprotected amine, nitro-reduction products) using gradient HPLC and UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, ethyl acetate, methanol) by gas chromatography with flame ionization detection against calibrated standards. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine generation in pyridine-free reagent system. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pd, Ni, Fe) after acid digestion using inductively coupled plasma mass spectrometry with isotope dilution. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content by ignition at 600 C followed by weighing of residual residue. |
| Optical Rotation | [a]D Measurement | Determines specific optical rotation using sodium D-line light to confirm chiral integrity and enantiomeric purity. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid, indicating crystallinity and absence of eutectic impurities. |
| pH of Aqueous Suspension | pH Meter | Evaluates acidity/basicity by measuring pH of saturated aqueous suspension to detect residual acidic/basic process impurities. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry powder particle size distribution using Mie scattering theory under controlled dispersion conditions. |
| Microbial Contamination | Membrane Filtration | Detects aerobic microorganisms by filtration, membrane transfer to agar media, and colony enumeration after incubation. |
