Industrial Applications of [2-(4-AMINO-PHENYL)-ETHYL]-CARBAMIC ACID TERT-BUTYL ESTER
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Intermediate for synthesizing linkers in targeted protein degradation chimeras (PROTACs) | Used in solid-phase or solution-phase synthesis to construct linker units containing an aniline-ethyl-malonic acid structure via coupling of the amino group with activated carboxylic acid derivatives (e.g., NHS esters) |
| Organic Synthesis | Multifunctional synthon providing a protected amino group and a deprotectable carboxylic acid functionality | The tert-butyl ester group is cleaved with trifluoroacetic acid (TFA) to yield the free carboxylic acid; the aromatic primary amino group participates in diazotization, acylation, alkylation, and other reactions to build heterocycles or coupling products |
Manufacturing Quality Control of [2-(4-AMINO-PHENYL)-ETHYL]-CARBAMIC ACID TERT-BUTYL ESTER
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identity | Fourier Transform Infrared Spectroscopy (FT-IR) | Confirms compound structure by identifying characteristic functional groups (e.g., amino, ester, tert-butyl) through their infrared absorption peaks. |
| Proton Nuclear Magnetic Resonance (¹H NMR) | Analyzes chemical shifts, integration areas, and coupling constants of hydrogen atoms to verify molecular structure and purity. | |
| Mass Spectrometry (MS or HRMS) | Determines molecular ion and fragment ions to confirm molecular weight and elemental composition; high-resolution MS can verify molecular formula. | |
| Assay | High-Performance Liquid Chromatography with UV detection (HPLC-UV) | Uses a reversed-phase C18 column and UV detector (typically 210–260 nm) to quantify the main component; concentration calculated using external standard method. |
| Gas Chromatography with FID/MS detection (GC-FID/MS)* | If the compound is thermally stable and volatile, GC may be used for assay (less common for highly polar compounds). | |
| Related Substances / Impurities | High-Performance Liquid Chromatography with DAD/UV detection (HPLC-DAD/UV) | Employs gradient elution to separate the main peak from potential impurities (e.g., starting materials, intermediates, degradation products); DAD detector aids in peak purity assessment. |
| Residual Solvents | Headspace Gas Chromatography with Flame Ionization Detection (HS-GC-FID) | Detects organic solvents (e.g., methanol, ethanol, dichloromethane, toluene) that may remain from synthesis or purification processes, in accordance with ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration | Accurately measures water content using volumetric or coulometric methods; suitable for moisture-sensitive organic compounds. |
| Melting Point | Melting Point Apparatus | Determines the temperature range at which the compound melts; serves as a physical constant for preliminary identification and purity evaluation (higher purity results in a narrower melting range). |
| Appearance and Color | Visual Comparison | Observes whether the sample is a white to off-white solid, free from foreign matter or abnormal coloration, meeting pharmacopoeial or internal specifications. |
| pH (if prepared as solution) | pH Meter | Measures the pH of a solution or suspension at a specified concentration to assess the influence of acidic or basic impurities (applicable for soluble salt forms). |
