Manufacturing Quality Control of 62459-02-3
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Identification | Infrared Spectroscopy (IR) | Determine the infrared absorption spectrum of the sample and compare it with standard spectra to confirm the presence of characteristic functional groups (e.g., amide, pyrimidine ring, etc.). |
| Proton Nuclear Magnetic Resonance (¹H NMR) | Use ¹H NMR to measure chemical shifts, integration areas, and coupling constants of hydrogen atoms in the compound to verify structural features. | |
| Mass Spectrometry (MS) | Obtain molecular ion and fragment ions via electrospray ionization (ESI) or electron ionization (EI) to confirm molecular weight and structural information. | |
| Assay | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with methanol/acetonitrile-water (containing buffer salt or acid) as mobile phase and a UV detector (e.g., 254 nm) to quantify the main component. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Using the same conditions as assay or a gradient elution program to separate and detect process impurities, degradation products, etc. Quantify using area normalization or relative response factors. |
| Residual Solvents | Gas Chromatography (GC) | Headspace or direct injection, using polar or non-polar capillary columns with FID detector, in accordance with ICH Q3C guidelines to detect residual organic solvents (e.g., methanol, dichloromethane, DMF, etc.). |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying Method | Dry the sample at a specified temperature (e.g., 105°C) to constant weight and calculate the percentage loss of moisture or other volatile components by mass. |
| Melting Point | Melting Point Apparatus | Determine the melting temperature range using capillary method or digital melting point apparatus as an auxiliary indicator of purity and identity. |
| Specific Optical Rotation (if chiral) | Polarimeter | If the compound has chiral centers and stereochemistry control is required, optical purity can be assessed by measuring optical rotation. |
| pH Value (if prepared as solution) | pH Meter | Dissolve the sample into an aqueous solution of defined concentration and measure its pH to evaluate whether acidity or alkalinity meets specifications. |
| Elemental Impurities | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | According to ICH Q3D requirements, detect potential heavy metal elemental impurities (e.g., catalyst residues such as Pd, Ni, etc.). |
