Industrial Applications of 85909-04-2
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Chemicals | Synthesis of peptide and protein therapeutics | Serves as a Boc-protected GABA derivative monomer for solid-phase or solution-phase peptide synthesis to construct specific amino acid sequences. |
| Pharmaceutical Chemicals | Preparation of pharmaceutical intermediates | Acts as a key synthetic building block in the synthesis of GABA-derived neurological drugs such as pregabalin. |
| Biochemistry | Synthesis of biochemical probes and labeling agents | Used to synthesize bioactive molecules bearing specific functional groups, introducing the GABA structural motif as a linker or spacer group. |
| Organic Synthesis | Protecting group chemistry | Leverages the controllable deprotection of the Boc group to construct libraries of linear fatty acid esters bearing protected primary amines, enabling subsequent derivatization reactions such as amination and reduction. |
Manufacturing Quality Control of 85909-04-2
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 210 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 relative to reference standards or threshold reporting. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., methanol, THF, DMF) based on calibrated external standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generation in pyridine-free reagent; measures water via stoichiometric reaction with iodine and sulfur dioxide. |
| Heavy Metals | ICP-MS | Multi-element detection after acid digestion; quantifies metals (e.g., Pb, Cd, Ni, Fe) by mass-to-charge ratio with isotopic resolution and low detection limits. |
| Chloride Content | Ion Chromatography | Separation of anions on anion-exchange column with suppressed conductivity detection; quantifies chloride as a common inorganic impurity. |
| Residual BOC Protecting Group | HPLC-UV | Specific assay for di-tert-butyl dicarbonate (Boc2O) and tert-butanol degradation products using isocratic HPLC-UV. |
| Optical Rotation | [alpha]D Measurement | Measurement of specific rotation using sodium D-line light source to confirm chiral integrity and absence of racemization. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition determination by observing solid-to-liquid phase change in capillary tube under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against established reference standards under controlled lighting conditions. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination of hydrogen ion activity in a saturated aqueous suspension using calibrated glass electrode and pH meter. |
| Residue on Ignition | Gravimetric Analysis | Weighing residue remaining after high-temperature ashing (700-800 C) to quantify non-volatile inorganic impurities. |
