Industrial Applications of 83255-86-1
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Intermediate for synthesizing kinase inhibitors (e.g., JAK and BTK inhibitors) | Prepared via nucleophilic substitution of 3-bromo-1H-pyrazolo[3,4-d]pyrimidine with ammonia or amine reagents |
| Pharmaceuticals | Construction of antitumor agents containing the pyrazolopyrimidine scaffold | Used as a key intermediate in multistep coupling, cyclization, or functional group transformation reactions |
| Chemical Research | Development of organic synthetic methodologies | Employed as an electrophilic reagent in transition metal-catalyzed cross-coupling reactions (e.g., Suzuki, Sonogashira) |
| Pharmaceuticals | Precursor for synthesizing selective protein kinase inhibitors | Amino group introduced via ammonolysis or amination, followed by further derivatization to construct the drug molecule |
Manufacturing Quality Control of 83255-86-1
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at characteristic wavelength, comparing peak area to reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities by retention time separation and UV response relative to main peak. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents using gas chromatography with flame ionization detection against calibrated standards. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration using iodine-based redox reaction specific to water. |
| Heavy Metals | ICP-MS | Determines trace metal contaminants (e.g., Pb, Cd, Ni) by plasma ionization and mass spectrometric detection. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfate Impurity | Ion Chromatography | Separates and quantifies sulfate ions using anion-exchange column and conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content after high-temperature incineration and weighing of residual solids. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using controlled heating and visual observation. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light and against standard references. |
| Bulk Density | USP <616> Tap Density Method | Measures mass per unit volume after standardized tapping of a powder sample in a graduated cylinder. |
| Microbial Contamination | Membrane Filtration | Detects viable aerobic microorganisms by filtration, membrane transfer to culture media, and colony enumeration. |
