Manufacturing Quality Control of 2-Methylpyrimidine
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Purity Analysis | High-Performance Liquid Chromatography (HPLC) | Uses a reversed-phase C18 column and UV detector (e.g., 254 nm), with methanol/water or acetonitrile/buffer salt as mobile phase, to quantify the purity of the main component and separate impurity peaks. Suitable for accurate determination of samples with purity ≥98%. |
| Impurity Content | HPLC or GC-MS | HPLC is used for non-volatile impurities; GC-MS is suitable for qualitative and semi-quantitative analysis of volatile organic impurities, identifying unknown impurity structures by matching with mass spectral libraries. |
| Moisture Content | Karl Fischer Titration | Based on electrochemical titration principle, where iodine reacts with sulfur dioxide in a pyridine/methanol system with water, enabling precise measurement of trace moisture in samples (typically required ≤0.5%). |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Residual solvents are released by heating the sample, separated on a capillary column, and quantified using FID or MS detectors. Commonly used to detect process-related residual solvents such as methanol, ethanol, and ethyl acetate. |
| Structural Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Confirms molecular structural integrity through analysis of characteristic chemical shifts and coupling constants in 1H NMR and 13C NMR spectra, ruling out interference from isomers or by-products. |
| Melting Point | Capillary Melting Point Apparatus | Determines the temperature at which a substance transitions from solid to liquid using a digital melting point apparatus (theoretical melting point of 2-methylpyrimidine is approximately 38–40°C) to assess crystalline purity and thermal stability. |
| Appearance and Color | Visual Comparison / Colorimeter | Visually inspect under standard lighting conditions for colorless to pale yellow liquid or crystals; alternatively, use a colorimeter to measure Lab* values for consistent control of product appearance. |
| pH Value (aqueous solution) | pH Meter Measurement | Prepare an aqueous solution of defined concentration and measure its acidity/basicity using a calibrated pH meter (2-methylpyrimidine is weakly basic, pH ≈ 8–9), to evaluate presence of acidic impurities. |
| Heavy Metal Residues | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | After microwave digestion of the sample, ICP-MS simultaneously detects residual levels of elements such as Pb, As, Cd, and Hg, ensuring compliance with ICH Q3D limits (typically ≤10–20 ppm). |
