Industrial Applications of FMOC-CYS(4-MBZL)-OH
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Synthesis | Used as an amino-protecting group in peptide synthesis | In solid-phase peptide synthesis (SPPS), the amino group of cysteine is protected with N-(9-fluorenylmethoxycarbonyl) (Fmoc), while the thiol group is protected with S-(4-methylbenzyl) to prevent oxidation and side reactions, enabling stepwise coupling and subsequent deprotection |
Manufacturing Quality Control of FMOC-CYS(4-MBZL)-OH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 260-280 nm. |
| Related Substances | HPLC-UV | Separation and detection of structurally related impurities (e.g., diastereomers, deprotection products, oxidation byproducts) using gradient HPLC with UV monitoring. |
| Chiral Purity | Chiral HPLC | Enantioselective separation on a chiral stationary phase to determine L-enantiomer excess and detect D-cysteine containing impurities. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify residual solvents (e.g., DMF, DCM, methanol) 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 with water. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic elements (e.g., Pb, Cd, As, Hg) after acid digestion, using inductively coupled plasma mass spectrometry for sub-ppb sensitivity. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after high-temperature ashing (500-600 C) and weighing. |
| Optical Rotation | [alpha]D Measurement | Determination of specific optical rotation using a polarimeter at specified concentration, temperature, and sodium D-line wavelength to confirm chiral integrity. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample via light scattering to determine D10, D50, D90 values per USP <429>. |
| pH of Solution | Potentiometric pH Measurement | Electrochemical measurement of hydrogen ion activity in a defined aqueous or aqueous-organic solution using calibrated pH electrode. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition range using controlled heating and visual or automated endpoint detection. |
| Microbial Limits | Membrane Filtration + Culture | Enumeration of aerobic microorganisms and detection of specified pathogens (e.g., E. coli, S. aureus) per USP <61> and <62>. |
