Manufacturing Quality Control of t-Boc-N-amido-PEG2-acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 210 nm, calibrated against reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time relative to reference standards. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection for quantitative analysis of common organic solvents (e.g., THF, DMF, ethyl acetate). |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content in the sample. |
| Acid Value | Acid-Base Titration | Neutralization of free carboxylic acid groups with standardized NaOH solution using phenolphthalein or potentiometric endpoint detection. |
| Residue on Ignition | Gravimetric Analysis | Heating sample at 750 C to constant weight and measuring non-volatile inorganic residue as percentage of initial mass. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and Ni after acid digestion, using inductively coupled plasma optical emission spectrometry. |
| Chloride Content | Ion Chromatography | Separation and quantification of chloride ions using suppressed conductivity detection after aqueous extraction. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of solid or solution under controlled white light against established reference standards. |
| Melting Point | Capillary Melting Point Determination | Thermal transition measurement using calibrated capillary apparatus with controlled heating rate (1-2 C/min). |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light at 20 C using sodium D-line (589 nm) to assess chiral purity. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion via laser scattering to determine D10, D50, and D90 values. |
