Manufacturing Quality Control of 655235-65-7
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 220-254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time relative to reference standards or threshold limits. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., methanol, dichloromethane) against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generation in pyridine-free reagent; water reacts stoichiometrically with iodine and sulfur dioxide. |
| Heavy Metals | ICP-OES | Multi-element quantification after acid digestion; detection based on characteristic atomic emission spectra of metals in plasma. |
| Chloride Impurity | Ion Chromatography | Separation of chloride anions on anion-exchange column with suppressed conductivity detection; quantified against sodium chloride standard. |
| Residue on Ignition | Gravimetric Analysis | Mass loss after high-temperature ashing (700-800 C); residue weight reflects inorganic ash content. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change; determined by controlled heating and visual observation of meniscus movement. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral centers in solution; reported as degrees per dm/g/mL. |
| Appearance | Visual Inspection | Assessment under controlled white light against defined standards for color, clarity, and physical state (e.g., white to off-white crystalline powder). |
| pH of Aqueous Suspension | pH Meter | Measurement of hydrogen ion activity in a standardized suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Bulk Density | USP <616> Tap Density Method | Determined by measuring mass per unit volume before and after mechanical tapping; used to assess flow and handling properties. |
