Manufacturing Quality Control of Dibenzyl diselenide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison against a certified reference standard using UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., benzyl selenol, dibenzyl disulfide) relative to main peak using gradient elution. |
| Residual Solvents | GC-FID | Detection and quantification of volatile solvents (e.g., toluene, ethanol) by flame ionization detection after headspace or direct injection. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content via reaction of iodine with sulfur dioxide in pyridine/methanol medium. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification of heavy metals (Pb, Cd, Hg, As) after acid digestion using plasma optical emission spectroscopy. |
| Selenium Content | ICP-OES | Direct measurement of total selenium concentration following microwave-assisted nitric acid digestion. |
| Acid Value | Acid-Base Titration | Neutralization of acidic impurities (e.g., benzoic acid) with standardized KOH solution using phenolphthalein indicator. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature range using calibrated capillary tube method under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of particulates or phase separation against established reference standards. |
| Residue on Ignition | Gravimetric Analysis | Weighing of non-volatile residue remaining after high-temperature ashing (700-800 C) of sample in platinum crucible. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with suppressed conductivity detection. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution of known concentration and path length. |
