Manufacturing Quality Control of 5-Mercapto-1-methyltetrazole
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Purity (Main Component Content) | High-Performance Liquid Chromatography (HPLC) | Uses a C18 reversed-phase column with gradient elution using water-methanol or acetonitrile. The main peak area is detected by UV detector (210–254 nm). Content is calculated using external or internal standard method, effectively separating impurities. |
| Impurity Profile (Related Substances) | HPLC-UV / HPLC-MS | Gradient elution HPLC combined with UV or mass spectrometry detection is used to identify and quantify known impurities (e.g., oxidation products, unreacted starting materials, dimers), in compliance with ICH Q3B guidelines. |
| Moisture Content | Karl Fischer Titration | Measures trace moisture in the sample through a quantitative reaction between water and an iodine-sulfur dioxide-pyridine-methanol system, suitable for controlling quality risks caused by hygroscopicity of the drug substance. |
| Sulfur Content (Thiol Quantification) | Iodometric Titration / Colorimetric Method (DTNB Method) | Utilizes the reaction of thiol groups (–SH) with iodine or 5,5'-dithiobis(2-nitrobenzoic acid) (DTNB) to form a yellow product. Thiol content is quantified via titration or spectrophotometry (412 nm). |
| Heavy Metal Residues | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, AAS or ICP-MS is used to determine the content of heavy metal elements such as lead, cadmium, mercury, and arsenic, in compliance with pharmacopoeia limits (e.g., ICH Q3D). |
| Residual Solvents | Gas Chromatography (GC) | Residual organic solvents such as ethanol, acetone, DMF, and acetonitrile are detected using headspace or direct injection GC-FID. Compliance with ICH Q3C standards is evaluated. |
| Melting Point | Melting Point Apparatus | The melting point range of the sample is measured by capillary method or automatic melting point apparatus (literature value ~158–162°C), used for preliminary identification and purity evaluation. |
| pH Value (Aqueous Solution) | pH Meter | The sample is prepared into a solution of specified concentration (e.g., 1% w/v), and the pH is measured using a calibrated pH meter to assess the impact of acidity/alkalinity on stability. |
| Particle Size Distribution (if solid powder) | Laser Diffraction / Microscopy | Applicable for powder samples to evaluate particle size distribution and its impact on dissolution and formulation processes, ensuring batch-to-batch consistency. |
| Inorganic Impurities (e.g., Chlorides, Sulfates) | Precipitation Turbidimetry (Pharmacopoeia Method) | After dissolving the sample in water, silver nitrate or barium chloride is added to produce a precipitate. The turbidity is compared with standard solutions to control the content of inorganic anion impurities. |
| Infrared Spectroscopy (IR) Identification | Fourier Transform Infrared Spectroscopy (FT-IR) | The infrared absorption spectrum of the sample is collected and compared with reference spectra to confirm molecular structural features (e.g., –SH, tetrazole ring vibrations), used for qualitative identification. |
