Industrial Applications of 119302-19-1
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Intermediate in the synthesis of steroidal drugs for developing anti-inflammatory, immunomodulatory, or hormonal compounds | Epoxide ring-opening, nucleophilic substitution, or reduction reactions in organic synthesis to construct complex steroidal frameworks |
| Medicinal Chemistry | Used in structure–activity relationship (SAR) studies and biological activity screening of androstane derivatives | Multi-step synthesis involving protecting group strategies, stereoselective reactions, and column chromatography purification |
| Biomedical Research | Tool compound for investigating mechanisms of steroid receptor interactions | Dissolved in solvents such as DMSO for cellular or enzymatic assays; not intended for clinical use |
Manufacturing Quality Control of 119302-19-1
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at characteristic wavelength based on peak area comparison to reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC-UV with suitable column and mobile phase; identified by retention time and response relative to main peak. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, acetone, ethyl acetate) by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine generation in pyridine-free reagent system based on stoichiometric reaction with water. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pb, Cd, As, Hg) after acid digestion using inductively coupled plasma mass spectrometry for ultra-trace multi-element detection. |
| Optical Rotation | [alpha]D Measurement | Measures specific optical rotation using sodium D-line light source to confirm chiral integrity and enantiomeric purity of the compound. |
| Melting Point | Capillary Melting Point Apparatus | Determines 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 dry or wet dispersion mode based on Mie scattering theory applied to laser light diffraction patterns. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic residue remaining after high-temperature ashing (600–800 C) followed by precise weighing of cooled crucible. |
| Chloride Impurity | Ion Chromatography | Quantifies chloride ions using suppressed conductivity detection after separation on anion-exchange column with carbonate/bicarbonate eluent. |
| Microbial Limits | Membrane Filtration | Determines total aerobic microbial count and absence of specified pathogens (e.g., E. coli, S. aureus) using membrane filtration followed by incubation on selective media. |
| Sterility | Direct Inoculation | Confirms absence of viable microorganisms by direct transfer of sample into fluid thioglycollate and soybean-casein digest media followed by incubation and growth observation. |
