Industrial Applications of 147118-35-2
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Chiral synthetic intermediate for antiviral drugs and antibiotics | Introduces alkene functionality via Wittig or Horner-Wadsworth-Emmons reactions to enable stereoselective synthesis of oxygen-containing heterocycles or unsaturated carboxylic acid derivatives |
| Organic Synthesis | Multifunctional building block for total synthesis of complex natural products | Serves as a C6 backbone precursor in multistep syntheses; functional group manipulation—such as desilylation, oxidation, or reduction—enables stepwise construction of molecular complexity |
Manufacturing Quality Control of 147118-35-2
| 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 against 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 | Measures volatile organic solvents using gas chromatography with flame ionization detection and external calibration. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration using iodine generation in pyridine-methanol solvent system. |
| Heavy Metals | ICP-MS | Quantifies trace metal contaminants (e.g., Pb, Cd, Ni) via plasma ionization and mass spectrometric detection. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Residual Siloxanes | GC-MS | Identifies and quantifies volatile siloxane impurities by gas chromatographic separation followed by mass spectral identification. |
| Optical Purity (Enantiomeric Excess) | Chiral HPLC | Resolves enantiomers on chiral stationary phase and calculates ee from peak area ratio of (3R) vs. (3S) forms. |
| Acid Value | Acid-Base Titration | Measures free carboxylic acid groups by titration with standardized NaOH solution using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration followed by precise weighing of residue. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry powder particle size distribution by measuring angular scattering pattern of laser beam passed through dispersed sample. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method under controlled heating rate. |
