| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Industry | Key pharmaceutical intermediate for the antiplatelet drug cilostazol | Used in nucleophilic substitution with 4-methoxyphenylpiperazine to construct the core structural scaffold of cilostazol |
| Chemical Synthesis | Organic synthesis intermediate | Applied in nucleophilic substitution reactions via its reactive 3-chloropropyl side chain to introduce functional groups and synthesize other derivatives |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison with a certified reference standard using reversed-phase chromatography and UV detection at ~220 nm. |
| Related Substances | HPLC-UV | Separation and quantification of structurally similar impurities (e.g., unreacted intermediates, dechlorinated or hydrolyzed derivatives) against qualified reference standards. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., acetone, methanol, DMF) using gas chromatography with flame ionization detection and external calibration. |
| Water Content | Karl Fischer Titration | Electrochemical titration measuring water via iodine–sulfur dioxide reaction in anhydrous methanol-based medium; coulometric or volumetric mode applicable. |
| Heavy Metals | ICP-MS | Multi-element trace metal quantification (e.g., Pb, Cd, Hg, As) after acid digestion, leveraging high sensitivity and isotopic resolution. |
| Chloride Content | Ion Chromatography (IC) | Specific anion separation and quantification of chloride ion using suppressed conductivity detection following aqueous extraction. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement by observing solid-to-liquid phase change under controlled heating rate per pharmacopeial standards (e.g., USP <741>). |
| Residue on Ignition | Gravimetric Analysis | Determination of inorganic ash content after high-temperature (600–800 °C) incineration and precise weighing of residual residue. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or dispersed powder to determine volume-weighted particle size distribution (D10, D50, D90) based on light scattering principles. |
| Bulk & Tapped Density | ASTM D6393 | Measurement of mass per unit volume for freely settled (bulk) and mechanically tapped (tapped) powder states to assess flowability and compressibility. |
| Microbial Limits | Membrane Filtration + Culture | Enumeration of aerobic microorganisms and absence testing for specified pathogens (e.g., E. coli, S. aureus) per ISO 11731/USP <61> and <62>. |
