Manufacturing Quality Control of BOC-D-CYS(BZL)-OH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at ~210 nm. |
| Chiral Purity | Chiral HPLC | Separation of D- and L-enantiomers on a chiral stationary phase; enantiomeric excess calculated from peak area ratio. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., DMF, methanol, toluene) using flame ionization detection after headspace or direct injection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration measuring water via stoichiometric reaction with iodine in pyridine/methanol-based reagent. |
| Heavy Metals | ICP-MS | Multi-element trace metal quantification (e.g., Pb, Cd, Hg, As) after acid digestion, based on mass-to-charge ratio detection. |
| Residual Palladium | ICP-OES | Quantification of palladium (from deprotection catalysts) by atomic emission spectroscopy following microwave-assisted acid digestion. |
| Related Substances | HPLC-UV | Detection and quantification of structurally related impurities (e.g., N-BOC-D-cysteine, S-benzyl-D-cysteine, diketopiperazine) using gradient RP-HPLC. |
| Optical Rotation | [α]D Measurement | Determination of specific rotation at 589 nm using a polarimeter; confirms chiral integrity and batch consistency. |
| Residue on Ignition | Gravimetric Analysis | Measurement of inorganic ash content after controlled high-temperature incineration (500–600 °C) and weighing. |
| pH (1% w/v aqueous suspension) | pH Meter | Electrochemical measurement of hydrogen ion activity in a standardized aqueous suspension using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or dispersed powder size distribution based on angular scattering intensity of laser light. |
| Microbial Contamination | Membrane Filtration & Plate Count | Enumeration of aerobic microorganisms (CFU/g) following filtration, membrane transfer to agar media, and incubation per Ph. Eur./USP <61>. |
