Industrial Applications of 170844-49-2
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Used in the synthesis of drug molecules containing a pyrrolidine moiety, such as antiviral, anti-inflammatory, or central nervous system–targeting candidates | Applied as a BOC-protected pyrrolidine carboxylate ester in multi-step organic synthesis for coupling, reduction, or deprotection reactions to construct complex molecular frameworks |
| Organic Synthesis Reagents | Served as a chiral building block or precursor to functionalized pyrrolidine derivatives for constructing heterocyclic compound libraries | Converted into corresponding carboxylic acids, amides, or alcohols via hydrolysis, aminolysis, or Grignard addition, enabling further functionalization |
| Drug Discovery | Employed as a structural optimization module in high-throughput screening or structure–activity relationship (SAR) studies | Used as a modifiable core structural unit in combinatorial or parallel synthesis to introduce diverse side chains for biological activity evaluation |
Manufacturing Quality Control of 170844-49-2
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 210 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and threshold limits per ICH Q3B. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection for quantification of Class 2 and 3 solvents (e.g., ethyl acetate, ethanol, toluene) per ICH Q3C. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content based on stoichiometric reaction. |
| Optical Rotation | [alpha]D Measurement | Measurement of specific optical rotation using a polarimeter at 20 C and sodium D-line (589 nm) to confirm chiral integrity. |
| Heavy Metals | ICP-MS | Quantitative analysis of Pb, Cd, Hg, As, and other toxic elements by inductively coupled plasma mass spectrometry after acid digestion. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using suppressed conductivity detection with anion-exchange column. |
| Residual Palladium | ICP-OES | Determination of palladium residue (e.g., from coupling catalysts) by inductively coupled plasma optical emission spectrometry. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against defined standards under controlled lighting conditions. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid transitions to liquid, using calibrated capillary apparatus per USP <741>. |
| pH of Aqueous Solution | pH Meter | Measurement of pH in a 1% w/v aqueous suspension using a calibrated pH electrode and buffer standards. |
| Loss on Drying | Gravimetric Analysis | Weight loss measured after drying sample at 60 C under vacuum for 2 hours, indicating volatile content including residual solvents and moisture. |
