Manufacturing Quality Control of Di-tert-butyl N,N-diisopropylphosphoramidite
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component by retention time and peak area comparison against certified reference standard. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Detects and quantifies volatile organic solvents based on partitioning into headspace and GC separation. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Measures water via electrochemical generation of iodine reacting stoichiometrically with water in anhydrous medium. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Determines acidic impurities by titration with standardized sodium hydroxide using phenolphthalein indicator. |
| Phosphorus Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantifies total phosphorus after acid digestion by measuring characteristic atomic emission lines. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separates and quantifies chloride ions using ion-exchange column and suppressed conductivity detection. |
| Heavy Metals (Pb, Cd, Hg, As) | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Detects trace heavy metals after microwave-assisted digestion by elemental mass-to-charge ratio measurement. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measures non-volatile inorganic residue after high-temperature ashing at 600 C. |
| Optical Rotation | Polarimetry | Determines specific rotation using plane-polarized light to assess chiral purity and enantiomeric excess. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against standard reference under controlled lighting conditions. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method. |
| pH of Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in a defined aqueous suspension or solution using calibrated glass electrode. |
