Manufacturing Quality Control of CHROMIUM (III) CHLORIDE TETRAHYDROFURAN COMPLEX
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (CrCl2(THF)2 content) | UV-Vis Spectrophotometry | Quantifies chromium(II) complex via absorbance at characteristic wavelength (e.g., ~550 nm) using molar absorptivity calibration. |
| Moisture Content | Karl Fischer Titration | Measures water by coulometric or volumetric reaction with iodine, sulfur dioxide, and base in anhydrous methanol medium. |
| Residual Solvent (THF) | Gas Chromatography (GC-FID) | Separates and quantifies tetrahydrofuran using a polar column and flame ionization detection against calibrated standards. |
| Chloride Ion Impurity | Potentiometric Titration with AgNO3 | Determines free chloride via argentometric titration using silver nitrate and a silver indicator electrode. |
| Heavy Metals (Pb, Ni, Fe, Cu) | ICP-OES | Simultaneously quantifies trace metal impurities after acid digestion by measuring element-specific atomic emission intensities. |
| Acidity (as HCl) | Acid-Base Titration | Titrates acidic impurities with standardized NaOH using phenolphthalein or potentiometric endpoint detection. |
| Appearance and Color | Visual Inspection | Assesses physical state, clarity, and color against standard references (e.g., APHA scale) under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary tube method per USP <741>. |
| Loss on Drying | Gravimetric Analysis | Measures mass loss after drying under specified vacuum and temperature conditions to assess volatile content. |
| Residual Chromium(III) Impurity | UV-Vis Spectrophotometry | Differentiates Cr(III) from Cr(II) complex via distinct absorption bands; Cr(III) shows broad band near 400–450 nm. |
| Organic Impurities (decomposition products) | HPLC-UV | Separates and detects non-volatile organic impurities using reversed-phase chromatography and UV detection at 220–280 nm. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution in suspension using Mie scattering theory and calibrated optical model. |
