Industrial Applications of 1,15-Dibromopentadecane
| Industry | Application | Process |
|---|---|---|
| Organic Synthesis | Intermediate for synthesizing nitrogen-containing heterocyclic compounds (e.g., imidazoline derivatives) | Undergoes nucleophilic substitution with amines, followed by cyclization to form heterocyclic structures |
| Pharmaceutical R&D | Building block for drug molecules, used in synthesizing antibacterial and antifungal active compounds | Acts as an alkylating agent in structural modification and scaffold construction of drug lead compounds |
| Materials Science | Monomer for liquid crystals and reagent for introducing functional polymer segments | Couples via bromo-terminated end-group with alkenes or hydroxyl-containing compounds to incorporate a flexible pentadecyl chain, thereby tuning phase transition temperature and dielectric anisotropy |
Manufacturing Quality Control of 1,15-Dibromopentadecane
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 1,15-dibromopentadecane peak area relative to internal/external standard using calibrated response factors. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies impurities (e.g., mono-brominated isomers, dibromo by-products) based on retention time and mass spectral matching. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Detects and quantifies volatile organic solvents (e.g., dichloromethane, hexane) via equilibrium vapor phase analysis. |
| Water Content | Karl Fischer Titration (Coulometric) | Measures trace water by electrochemical generation of iodine reacting stoichiometrically with water in anhydrous medium. |
| Acid Value | Acid-Base Titration (NaOH in ethanol) | Determines acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Compares sample color against platinum-cobalt standard solutions using visual assessment or absorbance at 455 nm. |
| Density | Digital Density Meter (Oscillating U-tube) | Measures mass per unit volume at specified temperature based on resonant frequency shift of a vibrating U-shaped tube. |
| Refractive Index | Abbe Refractometer | Determines ratio of light velocity in air vs. sample at 20 C using critical angle measurement of monochromatic light. |
| Halogen Content (Total Br) | Oxygen Flask Combustion followed by Potentiometric Titration | Converts organobromine to bromide ion via combustion; titrates Br- with silver nitrate using silver electrode detection. |
| Heavy Metals | ICP-OES after Acid Digestion | Quantifies metals (e.g., Pb, Cd, Hg, As) by plasma excitation and elemental emission intensity measurement. |
| Non-Volatile Residue | Gravimetric Analysis (Evaporation and Weighing) | Determines residue after evaporation of fixed volume under controlled temperature and pressure, then weighing dried residue. |
| Chiral Purity (if applicable) | Chiral Gas Chromatography | Resolves enantiomers using chiral stationary phase and quantifies enantiomeric excess via peak area ratio. |
