Industrial Applications of tert-Butyl (4-bromothiophen-2-yl)carbamate
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Chemicals | Pharmaceutical Intermediates | Serves as a building block for functionalization at the 4-position of the thiophene ring via Suzuki and other coupling reactions to synthesize drug molecules with defined biological activity. |
| Pharmaceutical Chemicals | Amino Group Protection | Employs tert-butoxycarbonyl (Boc) to protect the 2-amino group of thiophene, preventing unwanted side reactions during subsequent synthetic steps, followed by deprotection. |
| Organic Synthesis | Heterocyclic Compound Synthesis | Used to prepare multifunctionalized thiophene derivatives for materials science applications or for screening and development of bioactive molecules. |
| Research Reagents | Laboratory R&D | Applied in new drug screening, mechanistic studies of chemical reactions, and preparation of reference standards. |
Manufacturing Quality Control of tert-Butyl (4-bromothiophen-2-yl)carbamate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and detection of impurities using gradient HPLC with UV detection; identification and quantification relative to main peak. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents based on retention time and peak area. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine, sulfur dioxide, and base in methanol to determine water content by stoichiometric reaction. |
| Heavy Metals | ICP-MS | Quantitative determination of trace metal elements (e.g., Pb, Cd, Hg, Ni) after acid digestion using inductively coupled plasma mass spectrometry. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column and conductivity detection. |
| Residual Palladium | ICP-OES | Determination of palladium residue after microwave-assisted acid digestion using inductively coupled plasma optical emission spectroscopy. |
| Optical Rotation | [alpha]D Measurement | Measurement of specific rotation using a polarimeter at 20 degC and sodium D-line (589 nm) to assess chiral purity and identity. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition analysis by observing the temperature range over which solid-to-liquid phase change occurs under controlled heating. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles or discoloration against defined standards under controlled lighting. |
| Particle Size Distribution | Laser Diffraction | Analysis of particle size distribution in dry or suspended state using Mie scattering theory applied to laser light diffraction patterns. |
| Bulk Density | Tap Density Tester | Measurement of mass per unit volume after standardized tapping to evaluate powder flow and handling characteristics. |
