Manufacturing Quality Control of 277299-70-4
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identity | Infrared Spectroscopy (IR) | Measures the infrared absorption spectrum of the sample and compares it with standard spectra to confirm functional groups and structural features. |
| Proton Nuclear Magnetic Resonance (¹H NMR) | Uses nuclear magnetic resonance technology to analyze the chemical shift and coupling constants of hydrogen atoms, verifying molecular structure. | |
| Mass Spectrometry (MS) | Determines molecular ion peaks and fragment ions to confirm molecular weight and structural information. | |
| Assay | High-Performance Liquid Chromatography (HPLC) | Uses reversed-phase HPLC with a C18 column and UV detector (e.g., 254 nm) to quantitatively determine the main component content. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Uses the same conditions as the assay or an optimized gradient elution program to separate and quantify potential process impurities and degradation products. |
| Residual Solvents | Gas Chromatography (GC) | Uses headspace or direct injection with a FID detector to detect organic solvent residues according to pharmacopoeia methods (e.g., ICH Q3C). |
| Drying Loss | Thermogravimetric Analysis (TGA) or Oven Drying Method | Measures the mass loss due to water or volatile components by drying at a specified temperature (e.g., 105°C) until constant weight. |
| Melting Point | Melting Point Apparatus | Determines the melting temperature range using capillary method or digital melting point apparatus, serving as one of the indicators of purity. |
| Appearance and Physical Properties | Visual Inspection | Observes the color, crystal form, and odor of the sample to check if they conform to the standard description. |
| pH Value (if applicable) | pH Meter Measurement | If the sample is soluble in water or buffer solution, measure the pH value of the solution to assess whether it falls within the specified range. |
| Water Content | Karl Fischer Titration | Uses volumetric or coulometric methods to accurately determine the water content in the sample, especially suitable for compounds sensitive to moisture. |
