Manufacturing Quality Control of N-Methyl-D-aspartic acid
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Reverse-phase C18 chromatographic column and UV detector (typically at 210–220 nm) are used. The main component content is quantified via a standard curve, providing high resolution and accuracy. |
| Purity Analysis | High-Performance Liquid Chromatography (HPLC) | The number and area of impurity peaks are detected to calculate the total impurity content, assessing sample purity. It is commonly used for quality control of raw materials or intermediates. |
| Chiral Purity (Enantiomeric Impurities) | Chiral High-Performance Liquid Chromatography (Chiral HPLC) | A chiral stationary phase chromatographic column is used to separate D- and L-isomers, detecting the presence of L-impurities or other enantiomeric impurities. |
| Moisture Content | Karl Fischer Titration Method | Based on the reaction between iodine and sulfur dioxide in an anhydrous environment with water, it accurately measures the moisture content in samples, suitable for solid samples with low water content. |
| Residual Solvents | Gas Chromatography (GC) | In accordance with ICH guidelines, this method detects residual organic solvents (such as methanol, ethanol, dichloromethane, etc.) from the production process using an FID detector. |
| Heavy Metals | Atomic Absorption Spectrometry (AAS) or ICP-MS | Toxic elements such as lead, cadmium, mercury, and arsenic are measured. ICP-MS has higher sensitivity and can detect multiple elements simultaneously. |
| Ignition Residue (Sulfated Ash) | Gravimetric Method | After incineration at high temperature, sulfuric acid is added to the residue, and the weight of the remaining material is measured to assess the level of inorganic impurities. |
| pH Value | pH Meter Measurement Method | The sample is prepared into a solution of specific concentration (e.g., 1% w/v), and its acidity or alkalinity is measured using a calibrated pH meter. |
| Solubility | Visual Inspection or Turbidity Measurement | Observes the dissolution behavior of the sample in different solvents (water, ethanol, methanol, etc.) to determine whether its solubility meets the standard. |
| Crystal Form Analysis | X-ray Powder Diffraction (XRD) | Analyzes the crystal structure of solid samples to confirm the presence of polymorphic forms and ensure batch consistency. |
| Structural Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | ¹H-NMR and ¹³C-NMR are used to confirm the compound's structure, verifying the chemical structure and substitution positions of the target molecule. |
| Infrared Characteristic Absorption | Fourier Transform Infrared Spectroscopy (FTIR) | Confirms the presence of functional groups (such as carboxyl, amino, etc.) by comparing infrared absorption spectra with reference spectra, used for identity verification. |
