Manufacturing Quality Control of 84758-55-4
| 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 against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of structurally related impurities (e.g., Boc-deprotected acid, hydrolyzed ester, diastereomers) using gradient HPLC-UV. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify residual solvents (e.g., methanol, THF, ethyl acetate) per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content based on stoichiometric reaction. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, achieving sub-ppb sensitivity. |
| Optical Rotation | [α]D Measurement | Polarimetric measurement at 20 °C using sodium D-line (589 nm) to confirm chiral integrity and enantiomeric purity. |
| Residual Catalyst (Pd) | ICP-OES | Quantification of palladium residues after microwave-assisted acid digestion using plasma optical emission spectroscopy. |
| Acid Value | Acid-Base Titration | Titration with standardized NaOH solution using phenolphthalein indicator to assess free carboxylic acid from partial hydrolysis. |
| Residue on Ignition | Gravimetric Analysis | Ignition at 600–700 °C followed by weighing to determine inorganic ash content per USP <281>. |
| Particle Size Distribution | Laser Diffraction | Dry dispersion and light scattering analysis to characterize bulk powder morphology relevant to handling and formulation. |
| Microbial Contamination | Membrane Filtration | Enumeration of aerobic microorganisms and absence of specified pathogens per Ph. Eur. 2.6.12. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid-to-liquid phase transition occurs, indicating crystallinity and purity. |
| Infrared Absorption | FT-IR Spectroscopy | Comparison of sample IR spectrum against reference standard to verify functional groups (e.g., C=O ester, N–H carbamate, t-Bu). |
