Manufacturing Quality Control of H2N-PEG2-Propyne
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 200-220 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and detection of impurities using gradient HPLC-UV; identification and quantification against qualified impurity standards or threshold-based reporting. |
| Water Content | Karl Fischer Titration | Electrochemical titration with iodine reagent to determine water content based on stoichiometric reaction with iodine and sulfur dioxide in pyridine/methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700-800 C to volatilize organic matter, then weighing inorganic residue as sulfate ash. |
| Heavy Metals | ICP-OES | Multi-element detection after acid digestion; quantifies Pb, Cd, Hg, As, and other regulated metals by atomic emission intensity at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation of anions on an ion-exchange column with suppressed conductivity detection; quantifies chloride relative to calibration standards. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection; identifies and quantifies common solvents (e.g., methanol, THF, toluene) using internal standard calibration. |
| Acid Value | Acid-Base Titration | Titration with standardized NaOH solution using phenolphthalein indicator; measures free carboxylic acid or acidic degradation products. |
| Amine Content | Non-aqueous Acid-Base Titration | Titration with perchloric acid in glacial acetic acid using crystal violet indicator; determines total basic nitrogen content. |
| Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through solution; assesses chiral purity and absence of racemization. |
| Appearance | Visual Inspection | Comparison of sample solution (in specified solvent) against water or clear standard under controlled lighting; evaluates clarity and color. |
| pH (1% aqueous solution) | pH Meter Measurement | Potentiometric measurement using calibrated pH electrode in a 1% w/v aqueous solution at 25 C; indicates protonation state and hydrolytic stability. |
