Industrial Applications of (9H-fluoren-9-yl)methyl 2-hydroxyethyl(methyl)carbamate
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Protecting group reagent in drug synthesis | Used to protect secondary amines (e.g., N-methyl-2-hydroxyethylamine) with fluorenylmethyloxycarbonyl (Fmoc) for stepwise solid-phase or solution-phase synthesis of peptides or small-molecule drugs |
| Chemical Synthesis | Organic intermediate | Applied to protect amino groups via Fmoc introduction in carbonyl–amine condensation reactions, enabling subsequent molecular modification or coupling reactions |
| R&D | Peptide chemistry and asymmetric synthesis research | Employed as a derivatization reagent for the Fmoc protecting group in laboratory-scale synthetic route development and reaction condition optimization |
Manufacturing Quality Control of (9H-fluoren-9-yl)methyl 2-hydroxyethyl(methyl)carbamate
| 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 220 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC with UV detection; identification based on retention time matching and threshold limits per ICH Q3B. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., DMF, THF, methanol) against calibrated standards. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generation in pyridine-free reagent; measures total water content by stoichiometric reaction with Karl Fischer reagent. |
| Heavy Metals | ICP-MS | Quantitative determination of elemental impurities (e.g., Pb, Cd, Ni, As) after acid digestion, using inductively coupled plasma mass spectrometry for sub-ppb sensitivity. |
| Chloride Content | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column and suppressed conductivity detection. |
| Residual Catalyst (Pd) | ICP-OES | Determination of palladium residue after microwave-assisted acid digestion via inductively coupled plasma optical emission spectroscopy. |
| Optical Rotation | [alpha]D Measurement | Measurement of specific rotation using a polarimeter at 20 C and sodium D-line (589 nm) to confirm chiral integrity and enantiomeric consistency. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition analysis by controlled heating of crystalline sample in capillary tube; endpoint determined by complete disappearance of solid phase. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion using laser scattering principle to determine volume-based particle size distribution (D10, D50, D90). |
| Bulk Density | USP <616> Tap Density Test | Measurement of mass per unit volume before and after mechanical tapping to assess flowability and compaction behavior. |
| Microbial Limits | Membrane Filtration and Plate Count | Enumeration of aerobic microorganisms and detection of specified pathogens (e.g., E. coli, S. aureus) following USP <61> and <62>. |
