Industrial Applications of BOC-SER(TOS)-OCH3
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | As a serine derivative, used as a protecting-group intermediate in peptide synthesis | Applied in solid-phase or liquid-phase peptide synthesis (SPPS/LPPS), with BOC protecting the amino group, TOS protecting the hydroxyl group, and methyl ester protecting the carboxyl group—enabling selective deprotection and coupling |
| Biochemical Research | Used to construct peptide probes containing phosphoserine-mimicking structures | Applied in enzymology or signaling pathway studies, where deprotected intermediates are incorporated into phosphosite-mimicking peptide assembly |
| Organic Synthesis | Used as a chiral building block for constructing stereocenters in complex molecules | After selective removal of the BOC or TOS group, subjected to functional group transformation or carbon-chain elongation reactions |
Manufacturing Quality Control of BOC-SER(TOS)-OCH3
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 210 nm, calibrated against certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and peak area normalization. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., methanol, THF, toluene) per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water by electrochemical endpoint detection. |
| Heavy Metals | ICP-MS | Multi-element quantification of Pb, Cd, Hg, As, and other toxic metals after acid digestion, with detection at sub-ppt levels. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride anion in aqueous extract; quantified via external calibration. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after high-temperature ashing at 700-800 C and weighing. |
| Optical Rotation | [alpha]D Measurement | Determination of specific optical rotation using sodium D-line light source in a temperature-controlled polarimeter. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as solid-to-liquid phase change under controlled heating rate. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Electrochemical measurement using calibrated glass electrode in saturated aqueous suspension (1% w/v). |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion using laser scattering to derive volume-based size distribution (D10, D50, D90). |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic mesophilic microorganisms and absence testing for specified pathogens per USP <61> and <62>. |
