Industrial Applications of 4-(phenylmethoxycarbonylamino)benzoic acid
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Used as an intermediate in the synthesis of angiotensin-converting enzyme (ACE) inhibitors, such as enalapril | Constructs the drug molecule backbone via organic synthesis reactions including acylation and condensation |
| Chemical Research | Used as a protecting group reagent or structural building block in peptide and small-molecule synthesis | Introduces the benzyloxycarbonyl (Cbz) group to protect amines during solid-phase or solution-phase synthesis; subsequent deprotection enables target molecule assembly |
| Biochemistry | Used to prepare amino-protected probes or labeling agents for protein/peptide structural studies | After conjugation with biomolecules, analyzed and detected using chromatographic or mass spectrometric techniques |
Manufacturing Quality Control of 4-(phenylmethoxycarbonylamino)benzoic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and detection of structurally related impurities using gradient HPLC-UV; identification and quantification against reference standards or threshold limits. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify common organic solvents (e.g., methanol, acetone, toluene) based on retention time and peak area. |
| Heavy Metals | ICP-OES | Multi-element determination of Pb, Cd, Hg, As, and other regulated metals after acid digestion, using plasma optical emission spectroscopy. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode; endpoint detected by potential change due to AgCl precipitation. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample at 700-750 C followed by sulfuric acid treatment and final weighing of inorganic residue. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration with iodine-based reagent; water reacts stoichiometrically to generate endpoint current or voltage change. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition range using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of crystalline solid against defined standards under controlled lighting. |
| Particle Size Distribution | Laser Diffraction | Measurement of particle size distribution in dry or dispersed state using Mie scattering theory and laser diffraction optics. |
| Specific Optical Rotation | Polarimetry | Determination of chiral purity using sodium D-line light; rotation angle measured relative to path length and concentration. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined saturated aqueous suspension using calibrated pH electrode and temperature compensation. |
