Manufacturing Quality Control of 2-Thiouracil
| Test Item | Common Test Methods | Method Summary |
|---|---|---|
| Identification | Infrared Spectrophotometry (IR) | Determine the infrared absorption spectrum of the sample and compare it with standard spectra to confirm characteristic functional group absorption peaks of 2-thiouracil (such as C=S, N-H, etc.). |
| Ultraviolet-Visible Spectrophotometry (UV-Vis) | Measure maximum absorption at a specific wavelength (e.g., around 270 nm) and identify the compound based on the shape of the absorption spectrum. | |
| Assay | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with a mobile phase consisting of methanol-water or acetonitrile-water in an appropriate ratio. Quantify the main component using a UV detector, typically at 254 nm or 270 nm. |
| Non-aqueous Titration | Titrate in a non-aqueous solvent (e.g., glacial acetic acid) using perchloric acid as titrant, with crystal violet as indicator or potentiometric endpoint detection, to determine basic nitrogen content and indirectly assess the main component concentration. | |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Use gradient or isocratic elution to separate and detect potential impurities such as synthesis by-products or degradation products. Quantification is usually performed using the area normalization method or reference standard method. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Loss on Drying at Atmospheric Pressure | Dry the sample at a specified temperature (e.g., 105°C) until constant weight is achieved, then calculate the percentage weight loss to evaluate moisture and volatile content. |
| Sulfated Ash (Residue on Ignition) | High-Temperature Incineration | Ignite the sample at high temperature (typically 700–800°C), then weigh the residual inorganic matter to control total inorganic impurities. |
| Heavy Metals | Thioacetamide Method (Colorimetry) or Atomic Absorption Spectroscopy (AAS) | Determine total levels of heavy metal elements such as lead, cadmium, mercury, and arsenic through color-forming reactions or instrumental analysis to ensure compliance with pharmacopoeial limits. |
| pH Value | pH Meter Method | Prepare an aqueous solution of defined concentration (e.g., 1%), and measure acidity or alkalinity using a calibrated pH meter to reflect product purity and stability. |
