Industrial Applications of 903129-71-5
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Intermediate in the synthesis of antitumor agents | Used to construct the pyrrolo[3,4-d]pyrimidine scaffold; Boc-protected via multistep organic synthesis, followed by deprotection or coupling reactions to yield the target drug molecule |
| Organic Synthesis | Starting material for synthesizing novel heterocyclic compounds | Subjected to catalytic C–H functionalization and coupling reactions (e.g., Suzuki, Buchwald–Hartwig couplings) to build complex functional molecules |
| Chemical Research | Structural modification and structure–activity relationship (SAR) studies in new drug discovery | Serves as a core structural unit in high-throughput screening and structural optimization to evaluate biological activity and physicochemical properties |
Manufacturing Quality Control of 903129-71-5
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorption at specific wavelength using reverse-phase chromatography with calibrated standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities via retention time comparison and peak area integration. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., DMF, THF, methanol) using flame ionization detection after headspace or direct injection. |
| Water Content | Karl Fischer Titration | Determines trace water by electrochemical titration with iodine-based reagent reacting stoichiometrically with water. |
| Heavy Metals | ICP-MS | Quantifies toxic elements (Pb, Cd, Hg, As) at sub-ppb levels using mass spectrometry detection of elemental ions. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using conductivity detection after anion exchange separation. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content by high-temperature incineration followed by weight determination of residual solids. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using controlled heating and visual observation. |
| Specific Optical Rotation | Polarimetry | Measures chiral purity and identity by detecting rotation of plane-polarized light in solution. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry or wet dispersed sample to determine size distribution based on light scattering patterns. |
| Bulk Density | USP <616> Method I | Measures mass per unit volume of freely settled powder using standardized cylinder and tapping procedure. |
| Microbial Limits | Membrane Filtration | Detects aerobic microorganisms by filtration, membrane transfer to agar media, and colony enumeration after incubation. |
