Manufacturing Quality Control of 827614-66-4
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase chromatography with UV detection at ~254 nm, comparing peak area to a certified reference standard. |
| Related Substances (Impurities) | HPLC-UV/DAD | Separates and detects structurally related impurities (e.g., residual starting materials, de-borylated pyrazole, dimeric by-products) via gradient HPLC with diode-array detection. |
| Residual Solvents (e.g., THF, EtOAc, MeOH) | GC-FID | Quantifies volatile organic solvents by gas chromatography with flame ionization detection, using internal standard calibration. |
| Water Content | Karl Fischer Titration (Coulometric) | Determines trace water content electrochemically via iodine generation and stoichiometric reaction with water in anhydrous methanol-based reagent. |
| Inorganic Residues (Sulfated Ash) | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled high-temperature combustion (550–600 °C) and weighing of the ash. |
| Heavy Metals (Pb, Cd, Hg, As, Ni) | ICP-MS | Quantifies trace elemental impurities by inductively coupled plasma mass spectrometry with isotopic detection and matrix-matched calibration. |
| Residual Boron Content | ICP-OES | Measures total boron via inductively coupled plasma optical emission spectroscopy using characteristic B 249.773 nm emission line. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating crystallinity and presence of impurities. |
| Appearance & Color | Visual Inspection (against ISO 6271 or APHA scale) | Evaluates physical state (crystalline powder), color (white to off-white), and absence of visible particulates or discoloration under standardized lighting. |
| Loss on Drying (LOD) | Thermogravimetric Analysis (TGA) or Oven Drying | Measures weight loss upon heating under controlled conditions (e.g., 105 °C, 2 h) to quantify volatile matter including absorbed moisture and low-boiling residues. |
