Manufacturing Quality Control of 2,2'-BICINCHONINIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 220-280 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of structurally related impurities using gradient HPLC-UV, with detection and reporting relative to the main peak. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to react stoichiometrically with water in the sample dissolved in suitable solvent. |
| Residue on Ignition | Gravimetric Analysis | Heating sample at 700-800 C to constant weight and measuring non-volatile inorganic residue as percentage of original mass. |
| Heavy Metals | ICP-OES | Multi-element quantitative analysis of Pb, Cd, Hg, As, and other regulated metals after acid digestion and plasma excitation. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with conductivity detection. |
| Sulfate Impurity | Ion Chromatography | Separation and quantification of sulfate ions using anion-exchange column with conductivity detection. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution of known concentration and path length. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid transitions to liquid using calibrated capillary apparatus under controlled heating rate. |
| Solvent Residues (e.g., Ethanol, Acetone) | GC-FID | Quantitative analysis of residual solvents by gas chromatography with flame ionization detection using headspace sampling. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measurement of hydrogen ion activity in a saturated aqueous suspension using calibrated glass electrode and pH meter. |
| Appearance (Color and Clarity) | Visual Inspection | Comparison of sample solution or suspension against specified standards for color (e.g., APHA) and clarity (absence of particulates or haze). |
