Industrial Applications of 419563-23-8
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Pharmaceutical intermediates | Chiral synthesis process for preparing specific chiral pharmaceutical intermediates or raw materials. |
| Chemicals | Fine chemicals | Preparation of high-enantiomeric-purity compounds via asymmetric synthesis or resolution techniques. |
Manufacturing Quality Control of 419563-23-8
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 210–220 nm, comparing peak area against a qualified reference standard. |
| Chiral Purity | (S,S)- and (R,R)-Diastereomer Content | Chiral HPLC with chiral stationary phase (e.g., Chiralpak AD-H or OD-H), enabling baseline separation of diastereomers based on stereospecific interactions. |
| Optical Rotation | [α]D | Measurement of specific optical rotation at 589 nm (Na D-line) in specified solvent/concentration to confirm enantiomeric integrity and batch-to-batch consistency. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection for quantification of Class 2/3 solvents (e.g., methanol, THF, ethyl acetate, toluene) per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration quantifying trace water via iodine generation and stoichiometric reaction with water in anhydrous medium. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As, Ni, Pd) at sub-ppb levels using inductively coupled plasma mass spectrometry after acid digestion. |
| Residual Palladium | ICP-MS | Specific quantification of palladium residue (from prior catalytic steps) using isotope-dilution ICP-MS for high sensitivity and accuracy. |
| Related Substances | HPLC-UV (Forced Degradation Study) | Detection and quantification of structurally related impurities (e.g., deprotected amine, hydrolyzed ester, oxidation products) under stressed conditions (acid/base/oxidative/thermal). |
| Particle Size Distribution | Laser Diffraction | Dry or wet dispersion followed by light scattering analysis to determine D10, D50, D90 values relevant to filtration and formulation handling. |
| Residual tert-Butyl Carbamate (Boc) Cleavage Byproducts | GC-MS | Targeted detection and quantification of volatile cleavage fragments (e.g., isobutylene, tert-butanol, CO2-derived species) using gas chromatography–mass spectrometry. |
| Microbial Contamination | Membrane Filtration + TSA/TSA+CA | Enumeration of aerobic microorganisms and detection of specified pathogens (e.g., E. coli, S. aureus, P. aeruginosa, C. albicans) per USP <61> and <62>. |
