Manufacturing Quality Control of MES monohydrate
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Check whether the sample is a white to off-white crystalline powder, free from visible impurities or discoloration. |
| Identification | Infrared Spectroscopy (IR) | Compare the IR spectrum of the sample with that of the standard, confirming characteristic absorption peaks for functional groups such as sulfonic acid and morpholine ring. |
| Proton Nuclear Magnetic Resonance (¹H NMR) | Analyze proton chemical shifts in D₂O or DMSO-d₆, comparing with literature or standard spectra to confirm structure. | |
| Content (Purity) | High-Performance Liquid Chromatography (HPLC) | Use a C18 column with water-methanol or buffer solution as the mobile phase, UV detection at 210–220 nm, calculate the percentage of the main peak area, typically requiring ≥99.0%. |
| Titration Method (Acid-Base Titration) | Determine content by titrating with sodium hydroxide standard solution, using the strong acidity of the sulfonic acid group, and identifying the endpoint via potentiometry or indicator. | |
| Moisture Content | Karl Fischer Titration | Determine the content of crystalline and free water using coulometric or volumetric methods; usually requires 5.0%–6.5% (theoretical value ≈5.8%). |
| Residue on Ignition (Ash Content) | Ignition Residue Method | Incinerate the sample at high temperature (500–600°C), weigh the residue, and control the residue ≤0.1%. |
| Heavy Metals | Atomic Absorption Spectrometry (AAS) or ICP-MS | Process the sample according to pharmacopoeia methods (e.g., USP/EP), then determine the content of heavy metals such as lead, cadmium, mercury, and arsenic, meeting limits (e.g., ≤10 ppm). |
| Chlorides | Silver Nitrate Titration / Ion Chromatography | Determine chloride ions by precipitation with silver nitrate or use ion chromatography for quantification; control chlorides ≤0.05%. |
| Sulfates | BaCl₂ Turbidity Method | Add barium chloride after acidification of the sample, observe turbidity, and compare with standard solutions; control sulfates ≤0.02%. |
| pH Value (Solution) | pH Meter Measurement | Determine pH of a 1% aqueous solution at 25°C; typically requires a pH range of 5.5–7.0 (buffer performance verification). |
| Solubility | Physical Solubility Test | Observe solubility behavior in water, ethanol, ether, etc.; should be soluble in water, slightly soluble in ethanol, and insoluble in ether. |
| Microbial Limit (if applicable) | Plate Count Method / MPN Method | Detect total aerobic bacteria, molds and yeasts, and *Escherichia coli* according to pharmacopoeia regulations; applicable for pharmaceutical-grade products. |
| Particle Size Distribution (if applicable) | Laser Diffraction / Microscopy | For powdered formulations, measure particle size distribution to ensure flowability and uniformity (e.g., D90 < 100 μm). |
