| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Key chiral intermediate for the antiviral drug remdesivir, used to construct the core cyclic structure of nucleoside analogues | In the total synthesis of remdesivir, this compound serves as a C4-hydroxy/C6-amino bifunctional chiral building block in nucleoside side-chain construction, undergoing phosphorylation, glycosylation, and coupling steps |
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Chemical Structure Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Confirm atomic connectivity and stereochemistry within the molecule using ¹H-NMR, ¹³C-NMR, and 2D spectra (e.g., HSQC, HMBC). |
| Molecular Weight and Elemental Composition | High-Resolution Mass Spectrometry (HRMS) | Precisely measure the molecular ion peak to verify molecular formula, isotope distribution, and confirm the compound's molecular weight. |
| Chiral Purity / Stereochemistry | Chiral High-Performance Liquid Chromatography (Chiral HPLC) | Use chiral columns to separate enantiomers and assess the purity of the target stereoisomer (e.g., ee value). |
| Assay (Content Determination) | High-Performance Liquid Chromatography (HPLC-UV/ELSD) | Quantify the main component using reversed-phase or normal-phase chromatographic systems, with external standard or area normalization methods, ensuring compliance with specified limits. |
| Related Substances / Impurity Analysis | HPLC Gradient Elution Method | Optimize gradient programs to separate degradation products, process-related impurities, and stereoisomeric impurities for qualitative and quantitative control. |
| Water Content | Karl Fischer Moisture Determination | Accurately determine water content using volumetric or coulometric methods to prevent moisture-induced instability or altered reactivity. |
| Residual Solvents | Gas Chromatography (GC-FID/HS-GC) | Detect potentially residual organic solvents from synthesis using headspace or direct injection, in accordance with ICH Q3C guidelines. |
| Loss on Drying | Drying to Constant Weight (at 105°C) | Dry the sample at a specified temperature until constant weight is achieved, measuring total volatile content (including water and low-boiling solvents). |
| Heavy Metals / Elemental Impurities | ICP-MS or Atomic Absorption Spectroscopy (AAS) | Detect harmful elemental impurities such as Pb, As, Cd, and Hg in accordance with ICH Q3D to ensure compliance with safety limits. |
| Specific Optical Rotation | Polarimetry | Measure specific optical rotation at a specified wavelength (typically 589 nm) and concentration, serving as an auxiliary indicator for identity and purity of chiral compounds. |
| pH Value (for solution formulations) | pH Meter Measurement | Measure pH of liquid samples to evaluate acid-base stability and suitability. |
| Melting Point | Capillary Melting Point Apparatus | Determine the melting range of solid samples to assist in assessing purity and consistency of crystalline form (if applicable). |
