Industrial Applications of 306937-12-2
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Organic synthesis intermediate | Used in the synthesis of biologically active drug molecules, particularly as a key intermediate for constructing structural units containing amino and carboxyl functional groups |
| Pharmaceutical R&D | Peptide and small-molecule drug modification | Employs the BOC protecting group to protect amino groups, enabling selective reactions in multistep syntheses; the BOC group is subsequently removed via acid treatment |
| Fine chemicals | Preparation of functionalized aromatic compounds | Participates in Suzuki coupling, amide condensation, and other reactions to construct functionalized derivatives of complex aromatic systems |
| Materials science | Polymer precursor synthesis | Acts as a monomer or functionalized initiator in polymerization reactions to incorporate methoxy and carboxylic acid functional groups for material property modulation |
| Biochemistry | Probe molecule synthesis | Used to label or conjugate detection tags such as fluorescent probes and biotin, where the BOC group provides reaction orthogonality |
Manufacturing Quality Control of 306937-12-2
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and threshold limits per ICH Q3B. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify residual solvents (e.g., methanol, ethyl acetate) against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content via stoichiometric reaction. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, using isotopic detection for high sensitivity and specificity. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using suppressed conductivity detection with anion-exchange column. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample at 700-800 C followed by weighing of non-volatile inorganic residue after sulfuric acid treatment. |
| Optical Rotation | [alpha]D Measurement | Determination of specific optical rotation using sodium D-line light source in a polarimeter to confirm chiral integrity. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition analysis by observing solid-to-liquid phase change range under controlled heating rate. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample using Mie scattering theory to derive volume-based particle size distribution. |
| Bulk Density | USP <616> Method I | Measurement of mass per unit volume of powder poured freely into a graduated cylinder without compaction. |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic microorganisms and detection of specified pathogens (e.g., E. coli, S. aureus) per USP <61> and <62>. |
