Manufacturing Quality Control of Fmoc-Tyr(tBu)-OH
| Test Item | Common Testing Methods | Method Summary |
|---|---|---|
| Appearance | Visual Inspection | Visually examine the sample for color, physical state (e.g., white to off-white crystalline powder), and presence of visible foreign matter to determine compliance with specifications. |
| Identification | Infrared Spectroscopy (IR) High-Performance Liquid Chromatography (HPLC) Proton Nuclear Magnetic Resonance (¹H NMR) |
IR: Compare the infrared absorption spectrum of the sample with that of a reference standard; HPLC: Confirm identity by matching retention time with reference standard; ¹H NMR: Verify characteristic chemical shift peaks (e.g., aromatic protons, tert-butyl signals) consistent with the theoretical molecular structure. |
| Purity / Related Substances | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with gradient elution employing acetonitrile-water or methanol-water as mobile phase. Determine purity by peak area normalization and identify/quantify potential impurities (e.g., deprotection by-products, oxidation products). |
| Specific Optical Rotation | Polarimetry | Measure the optical rotation of the sample solution at a specified wavelength (typically sodium D line, 589 nm) and temperature, then calculate the specific rotation to verify optical purity and configuration (L-isomer should exhibit a specific positive range). |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Atmospheric Drying Method | Dry the sample at a specified temperature (e.g., 105°C) until constant weight is achieved, then determine the percentage weight loss to assess moisture and volatile content. |
| Sulfated Ash / Residue on Ignition | High-Temperature Ashing Method | Ignite the sample at high temperature (typically 700–800°C), then weigh the residual inorganic matter to control inorganic impurities (e.g., metal catalyst residues). |
| Water Content | Karl Fischer Titration | Determine water content using volumetric or coulometric Karl Fischer titration to ensure compliance with storage and reaction stability requirements. |
| Residual Solvents | Gas Chromatography (GC) | Use headspace or direct injection GC to detect organic solvents potentially remaining from synthesis or purification (e.g., dichloromethane, DMF, ethanol), with limits controlled according to ICH Q3C guidelines. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Digest the sample and measure concentrations of heavy metal elements such as lead, cadmium, mercury, and arsenic to ensure compliance with pharmacopoeial or customer-specified limits. |
