Industrial Applications of 162536-40-5
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Industry | Intermediate | Serves as a key intermediate in the synthesis of specific drug molecules, including certain antiviral and anticancer agents. |
Manufacturing Quality Control of 162536-40-5
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 210-230 nm, comparing peak area to reference standard. |
| Chiral Purity | (R,R)- and (S,S)-Diastereomer Content | Chiral HPLC with polysaccharide-based column and UV detection; separates diastereomers based on stereoselective interactions. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., THF, EtOAc, MeOH) using flame ionization detection after headspace or direct injection. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration using iodine generation and stoichiometric reaction with water. |
| Heavy Metals | ICP-MS | Quantifies trace metals (Pb, Cd, Hg, Ni, etc.) by plasma ionization and mass spectrometric detection of elemental isotopes. |
| Chloride Ion Impurity | Ion Chromatography | Separates and quantifies chloride anion using suppressed conductivity detection after anion-exchange separation. |
| Residual tert-Butyl Carbamate | GC-MS | Identifies and quantifies Boc group degradation products (e.g., tert-butanol, isobutylene) by gas chromatographic separation and mass spectral confirmation. |
| Related Substances | HPLC-DAD | Detects and semi-quantifies structurally related impurities using photodiode array detection across multiple wavelengths. |
| Optical Rotation | Polarimetry | Measures specific rotation at sodium D-line (589 nm) to confirm chiral integrity and batch-to-batch consistency. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using controlled heating and visual observation. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of particulates or foreign matter against established reference standards. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content after high-temperature incineration and weighing of residual sulfate-free residue. |
