Manufacturing Quality Control of N-(P-TOLUENESULFONYL)-L-PHENYLALANINE
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe sample color, physical form (e.g., white or off-white crystalline powder), and check for foreign matter, moisture absorption, or caking. |
| Purity | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with a UV detector (e.g., 220 nm or 254 nm); quantify main component purity by peak area normalization or external standard method. |
| Related Substances | HPLC (Gradient Elution) | Employ gradient elution to separate impurities; compare with reference standards of known impurities or use relative retention times to quantify individual impurity levels. |
| Melting Point | Capillary Melting Point Determination | Determine the melting temperature range according to pharmacopoeial methods to assess crystallinity and purity (typical value approximately 130–135°C). |
| Specific Optical Rotation | Polarimetry | Measure optical rotation at a specified wavelength (usually sodium D line, 589 nm) and concentration to confirm chiral configuration (L-configuration). |
| Loss on Drying | Weight Loss upon Drying (105°C to Constant Weight) | Weigh sample in a pre-weighed, constant-weight weighing bottle; dry at 105°C until constant weight is achieved, then calculate percentage weight loss to evaluate moisture and volatile content. |
| Sulfated Ash | High-Temperature Ashing in Muffle Furnace | Char the sample and then incinerate at 600–800°C; weigh the residual inorganic material to estimate total inorganic salts or metal impurities. |
| Heavy Metals | Thioacetamide Method or ICP-MS | Perform limit test using thioacetamide colorimetric method per Chinese Pharmacopoeia, or use ICP-MS for precise determination of elemental contents such as lead, arsenic, cadmium, and mercury. |
| pH Value | pH Meter Measurement (in aqueous solution or buffer) | Prepare a solution of defined concentration in water, measure pH using a calibrated pH meter to assess acidity or basicity (typically slightly acidic). |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | According to ICH Q3C guidelines, analyze residual organic solvents (e.g., methanol, ethanol, ethyl acetate) using capillary GC-FID or GC-MS. |
| Structural Confirmation | Infrared Spectroscopy (IR), Nuclear Magnetic Resonance (NMR) | IR: Compare characteristic functional group absorption peaks; NMR: Use ¹H/¹³C NMR to confirm molecular structure, substitution patterns, and stereochemistry. |
| Assay | HPLC External Standard Method or Non-aqueous Titration | HPLC external standard method: Quantify using a calibration curve established with reference standard; non-aqueous titration: Titrate amino groups with perchloric acid in glacial acetic acid medium. |
