Manufacturing Quality Control of CHEMBRDG-BB 4303055
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities by gradient HPLC-UV; identification based on retention time matching and threshold limits per ICH Q3B. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify residual solvents (e.g., isopropanol, acetone, toluene) against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generation in pyridine-free reagent; measures water via stoichiometric reaction with iodine and sulfur dioxide. |
| Heavy Metals | ICP-MS | Multi-element quantification of Pb, Cd, Hg, As, and others after acid digestion, using isotopic detection for sub-ppq sensitivity. |
| Chloride Impurity | Ion Chromatography | Separation of chloride anion on an anion-exchange column with suppressed conductivity detection, calibrated against NaCl standards. |
| Sulfated Ash | Gravimetric Analysis | Ignition at 700-750 C followed by weighing of inorganic residue after treatment with sulfuric acid and repeated incineration. |
| Optical Rotation | [alpha]D Measurement | Measurement of specific rotation using a digital polarimeter at 20 C with sodium D-line (589 nm), reporting degrees per dm·g/mL. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, using calibrated capillary method per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against water-white standard under controlled white light and specified viewing conditions. |
| Acid Value | Acid-Base Titration | Titration with standardized KOH ethanol solution using phenolphthalein indicator; measures free carboxylic acid or acidic impurities. |
| Residue on Ignition | Gravimetric Analysis | Weighing of non-volatile residue after ignition at 600 C for 30 minutes, following USP <281> procedure. |
