Manufacturing Quality Control of t-boc-N-amido-PEG2-bromide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 210 nm, comparing peak area to a certified reference standard. |
| Residual Solvents | GC-FID | Separation and quantification of volatile organic solvents (e.g., THF, DCM, MeOH) using capillary GC with flame ionization detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on the stoichiometric reaction of iodine with water in a pyridine-methanol buffer. |
| Acid Value | Acid-Base Titration | Titration with standardized NaOH solution using phenolphthalein indicator; measures free carboxylic acid or acidic impurities. |
| Bromide Ion Content | Ion Chromatography (IC) | Separation of bromide anions on an anion-exchange column with suppressed conductivity detection. |
| Heavy Metals | ICP-OES | Multi-element quantification after acid digestion, based on atomic emission intensities at element-specific wavelengths. |
| Residual Catalyst (Pd) | ICP-MS | Ultra-trace detection of palladium via mass spectrometry following microwave-assisted acid digestion. |
| Related Substances | HPLC-DAD | Identification and quantification of structurally related impurities using diode array detection and retention time matching. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature range at which solid-to-liquid phase change occurs. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against established reference standards under controlled lighting. |
| Loss on Drying | Gravimetric Analysis | Mass loss measured after drying under specified temperature and vacuum conditions, indicating volatile content. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral centers in solution at specified concentration and wavelength. |
