| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Used as a synthetic intermediate in drug manufacturing | Reacted with various compounds to produce specific pharmaceutical products |
| Chemicals | Used to synthesize other organic compounds | Converted into target products via reactions such as esterification and amidation |
| Research | Used as an analytical reagent or reference standard | Employed directly or in specific chemical reactions to study its properties and application potential |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 210-230 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., starting materials, intermediates, degradants) using gradient HPLC with UV detection and relative response factors. |
| Residual Solvents | GC-FID | Measures residual organic solvents (e.g., methanol, ethyl acetate, toluene) by headspace GC with flame ionization detection against calibrated standards. |
| Water Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine-based reagent where water reacts stoichiometrically with iodine and sulfur dioxide. |
| Heavy Metals | ICP-MS | Quantifies trace heavy metals (e.g., Pb, Cd, Ni, Fe) after acid digestion using inductively coupled plasma mass spectrometry for multi-element detection at sub-pptr levels. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with suppressed conductivity detection against chloride standard calibration. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after controlled combustion of sample with sulfuric acid treatment and high-temperature incineration, followed by weighing. |
| Optical Rotation | [alpha]D Measurement | Determines specific optical rotation using a polarimeter at 20 C and sodium D-line (589 nm) to confirm chiral integrity and enantiomeric purity. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid using calibrated capillary apparatus per USP <741>. |
| Particle Size Distribution | Laser Diffraction | Analyzes particle size distribution in suspension using Mie theory-based light scattering pattern analysis. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Determines pH of 1% w/v aqueous suspension using calibrated pH electrode and standardized buffer solutions. |
| Microbial Contamination | Membrane Filtration | Quantifies aerobic microorganisms and detects specified pathogens (e.g., E. coli, S. aureus) by filtration, culture on selective media, and colony enumeration. |
