Industrial Applications of L-Ser(Bzl)-OtBu.HCl
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Serine protecting reagent in peptide synthesis | Used in solid-phase or solution-phase peptide synthesis to selectively protect the serine side-chain hydroxyl group (O-benzyl) and the α-amino group (tert-butoxycarbonyl, as hydrochloride salt), facilitating subsequent deprotection and coupling reactions; the O-benzyl group is acid-stable and removable by hydrogenolysis, while the Boc group is base-stable and cleavable under mild acidic conditions (e.g., TFA) |
| Organic Synthesis | Chiral intermediate construction | Employed as a chiral building block bearing two orthogonal protecting groups in asymmetric synthesis, cyclization reactions, or enzymatic transformations to construct side-chain architectures of complex molecules such as β-lactam antibiotics and protease inhibitors |
Manufacturing Quality Control of L-Ser(Bzl)-OtBu.HCl
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by retention time and UV absorbance relative to reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient elution and UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., DCM, MeOH, EtOAc) via flame ionization detection after headspace or direct injection. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration with iodine-based reagent in pyridine-free medium. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Heavy Metals | ICP-MS | Detects trace metal contaminants (e.g., Pb, Cd, Ni) by mass spectrometric analysis of plasma-ionized sample. |
| Optical Rotation | [alpha]D Measurement | Measures specific rotation at 589 nm to confirm chiral integrity and enantiomeric purity. |
| Residual Palladium | ICP-MS | Quantifies residual Pd catalyst from synthesis using high-sensitivity mass spectrometry. |
| Loss on Drying (LOD) | Gravimetric Analysis | Determines volatile content by weight loss after controlled heating under specified temperature and vacuum conditions. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity in a defined aqueous suspension using calibrated glass electrode. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of solid particles in suspension by angular scattering intensity of laser beam. |
| Microbial Limits | Membrane Filtration | Detects aerobic microorganisms via filtration, membrane transfer to culture media, and colony enumeration. |
