Manufacturing Quality Control of Boc-L-Tyr(tBu)-OH
| Detection Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample under natural light or standard illumination for color and physical state (typically white to off-white crystalline powder), and assess compliance with specified criteria. |
| Identification | Infrared Spectroscopy (IR) High-Performance Liquid Chromatography (HPLC) |
IR: Obtain infrared absorption spectrum of the sample and compare with reference spectrum; HPLC: Under specific chromatographic conditions, the retention time of the main peak in the sample should match that of the reference standard. |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with appropriate acetonitrile-water or methanol-water mobile phase; detect using UV detector (typically 210–220 nm); calculate content by external standard method. Generally requires ≥98.0%. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Apply gradient or isocratic elution program to separate and detect potential process impurities and degradation products. Individual impurities typically ≤0.5%, total impurities ≤1.0%. |
| Specific Rotation | Polarimeter Method | Prepare a solution at a specified concentration (e.g., 1% w/v, in ethanol or water), measure optical rotation at a defined wavelength (usually sodium D line, 589 nm) and temperature (e.g., 20°C or 25°C), then calculate specific rotation. Should fall within the literature range (e.g., -7° to -9°). |
| Drying Loss | Thermogravimetric Analysis (TGA) or Constant-Temperature Drying at Atmospheric Pressure | Dry the sample at 105°C until constant weight; determine the percentage of mass loss. Typically requires ≤0.5%. |
| Residue on Ignition | High-Temperature Ashing Method | Char the sample, then ignite at 700–800°C in a muffle furnace; weigh the residual inorganic matter. Usually requires ≤0.1%. |
| Water Content | Karl Fischer Titration | Determine water content using either volumetric or coulometric Karl Fischer titration. Typically requires ≤0.5%. |
| Residual Solvents | Gas Chromatography (GC) | Based on ICH Q3C guidelines, use headspace GC to detect organic solvents (e.g., dichloromethane, methanol, ethyl acetate) potentially remaining from synthesis, ensuring compliance with specified limits. |
| pH Value (if applicable) | pH Meter Method | Prepare an aqueous solution at a specified concentration (e.g., 1%), measure pH using a calibrated pH meter. Typically neutral or slightly acidic. |
