Manufacturing Quality Control of 2,3-Dihydropyrido[2,3-d][1,3]oxazol-2-one
| Detection Item | Common Detection Method | Method Overview |
|---|---|---|
| Structural Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Analyze hydrogen and carbon atom chemical shifts and coupling constants using ¹H-NMR, ¹³C-NMR, to confirm the molecular skeleton structure. |
| Purity Determination | High-Performance Liquid Chromatography (HPLC) | Use a C18 reverse-phase column with a UV detector (e.g., 254 nm), and quantify the main component purity using external standard or area normalization methods. |
| Related Substances (Impurities) | HPLC Gradient Elution Method | Optimize the gradient elution program to separate potential process impurities and degradation products, and set impurity limits (e.g., single impurity ≤ 0.1%). |
| Drying Loss | Drying Method / Karl Fischer Titration | Dry at 105°C until constant weight, calculate the percentage of loss; or precisely determine crystalline or adsorbed water content using the Karl Fischer titration method. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Separate residual solvents such as methanol, ethyl acetate, etc., using a capillary column according to ICH Q3C, and quantify using an FID detector. |
| Melting Point | Capillary Melting Point Apparatus Method | Determine the temperature range from initial melting to complete melting, assessing crystalline purity and crystallinity consistency. |
| Heavy Metals | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Dissolve the sample and measure the total content of elements such as lead, cadmium, mercury, and arsenic, complying with ICH Q3D limits. |
| Optical Rotation (if chiral) | Polarimeter Method | If the molecule has a chiral center, measure the optical rotation of a solution of specific concentration under the sodium D line, controlling enantiomeric purity. |
| pH Value (for solutions) | pH Meter Method | Prepare a solution of certain concentration, directly measure the pH value, and assess acid-base stability or formulation compatibility. |
| Residue on Ignition | High-Temperature Ashing Method | After high-temperature (600–800°C) ashing, weigh the remaining inorganic matter to control inorganic salts or catalyst residue. |
