Manufacturing Quality Control of L-Glutamic acid α-tert·butyl ester
| Milestone | Common Testing Methods | Method Overview |
|---|---|---|
| Chemical Structure Confirmation | Nuclear Magnetic Resonance (NMR) | Using ¹H-NMR and ¹³C-NMR to analyze the chemical shift of hydrogen and carbon atoms in the molecule, confirming the structure of the target compound. |
| Purity Analysis | High-Performance Liquid Chromatography (HPLC) | Using a reversed-phase chromatography column with a UV detector (e.g., 210 nm) to quantitatively determine the main component and calculate the purity percentage. |
| Enantiomeric Purity (Optical Purity) | Chiral High-Performance Liquid Chromatography (Chiral HPLC) | Using a chiral stationary phase column to separate L/D isomers and evaluate the enantiomeric excess (e.e.%), ensuring the purity of the L configuration. |
| Moisture Content | Karl Fischer Titration | Determining trace moisture using coulometric or volumetric methods to control product stability and storage conditions. |
| Residual Solvents | Gas Chromatography (GC) | Using headspace or direct injection combined with a FID detector to quantify residual organic solvents (e.g., methanol, ethyl acetate). |
| Melting Point Determination | Digital Melting Point Apparatus | Determining the phase transition temperature from solid to liquid, serving as a physical constant for identification and purity assessment. |
| Heavy Metal Residues | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) or Atomic Absorption Spectroscopy (AAS) | Detecting the content of harmful heavy metals such as lead, arsenic, cadmium, and mercury, complying with pharmacopoeia or ICH Q3D standards. |
| Drying Loss | Oven Drying Method | Drying the sample to constant weight under specified temperature (e.g., 60–80°C) and vacuum conditions to measure the proportion of volatile substances lost. |
| pH Value (in Solution) | pH Meter Measurement | Measuring the pH value of the sample prepared into a solution of certain concentration to assess its acidity/alkalinity and stability. |
| Appearance and Physical Properties | Visual Inspection + Microscope Observation | Observing color, crystal form, particle size, and other physical properties to meet the requirements described in standard reference materials. |
